Sailing Footwear Compared: Dubarry, Zhik, Gill and Sail Racing

This is an objective comparison, not a hands-on test. Figures are the makers' published specifications.

Deck footwear is a materials problem, not a fashion one: soft high-hysteresis rubber and fine siping for traction on a wet, hard, low-texture surface; a drainage architecture that clears green water fast; and a last stiff enough to transmit deck feel without folding when you edge on a toerail. Four brands, two archetypes — the get-wet-and-drain racing shoe and the keep-dry offshore boot. For the fundamentals see our guide to sailing boots and shoes and the footwear research note.

At a glance

The two archetypes

Everything in this category resolves to one of two design intents, and confusing them is the usual buying mistake.

• The get-wet-and-drain shoe. Assumes the foot will be soaked and optimises for what happens next: shed the water in seconds, dry fast, stay light, keep the ankle free. Zhik's ZKG, Gill's Race Trainer and the Sail Racing x On Cloud Regatta are this archetype.
• The keep-dry boot. Assumes cold conditions where a wet foot is a liability and builds a waterproof-breathable barrier — neoprene or a GORE-TEX laminate — around the foot, accepting weight and slower drainage as the cost. Dubarry's leather boots, Gill's Offshore Boot and Zhik's 270/470 neoprene boots are this archetype.

For a Melges 40 sailed inshore in a Grand Prix circuit the first archetype wins on almost every warm-weather day; the second is a cold-water and delivery tool.

Sole and grip — the part that actually matters

The physics, briefly

On a hard, low-texture, wet surface — gelcoat non-skid, painted alloy, a smooth carbon cockpit sole, wet GRP — traction is governed by three levers, none of which is tread depth:

1. Compound. Soft, high-hysteresis rubber (roughly low-50s to low-60s Shore A) deforms into the micro-texture and dissipates energy at the contact patch. Too hard and it skates; too soft and it abrades away and can smear. The hard part is holding that softness across temperature — a compound that is grippy at 25°C can glaze and go slick when cold, which is exactly when you need it offshore.
2. Siping. Hundreds of fine razor cuts open under load to break the water film and give thousands of biting edges, letting the rubber contact the deck instead of aquaplaning on a trapped layer. This is the single most important geometric feature and the reason racing soles look nearly flat, not knobbly.
3. Contact area at low unit pressure. Maximise real rubber-on-deck area. Deep lugs reduce it and trap water — the opposite of what a wet hard deck wants. (Lugs only earn their keep on soft ground, which is why the same brands' hiking soles look completely different.)

How the four compare

Zhik — ZK Sole. Zhik's headline claim is process, not marketing gloss: the ZK Sole compound and tread were refined by testing on professional roofers working all day on steep, wet surfaces — a defensible proxy for the "soft, awash, moving underfoot" problem. The result is a fine-siped, near-flat contact zone in a non-marking compound tuned to stay pliable when cold. On the ZKG shoe this is paired with a skate-style toe and heel cap for durability at the scuff points. It is, on the published logic, the most deliberately engineered-for-wet-hard-deck compound of the four.

Gill — razor-cut outsole. Gill runs a genuine razor-cut (siped) non-marking outsole across the range and, on the Race Trainer, quotes multi-directional water-dispersion channels engineering "at least 80% foot contact" — an explicit statement of the contact-area lever above. The compound is specified to work wet and dry. Gill does not publish a durometer, so cold-temperature behaviour is inferred rather than stated; treat that as a genuine unknown.

Dubarry — NonSlip-NonMarking. Dubarry's award-winning NonSlip-NonMarking outsole uses a cast water-dispersion channel system explicitly aimed at eliminating aquaplaning, over a duo-compound PU midsole that adds shock absorption and structure. It is an excellent boot sole — it has to carry a heavier, stiffer boot and resist side load — but it is tuned for that duty, not for the low-mass, high-mobility inshore-shoe job.

Sail Racing x On — Missiongrip-derived compound. The Cloud Regatta is co-developed with On (the Swiss running-shoe engineering firm) and carries a proprietary rubber-reinforced deck-contact zone descended from On's Missiongrip sticky-rubber lineage, laid over the outsole drainage architecture (below). Bringing a running-shoe traction programme to a sailing sole is unusual and credible: the wet-hard-surface grip problem is one running R&D has spent heavily on. On merit this is a serious grip system, not a badge exercise.

Where they genuinely diverge: Zhik and Sail Racing lead on shoe compound engineering (roofer-refined vs running-R&D-derived, both near-flat and finely siped); Gill is close and quotes the useful contact-area figure; Dubarry's sole is optimised for boot duty and side-load, not inshore mobility. None publish a Shore A hardness, so cold-glazing resistance is the honest unknown across all four.

Drainage architecture — the make-or-break for a racing shoe

A get-wet shoe lives or dies on how fast it clears green water. This is a structural feature, not a fabric.

• Zhik ZKG is built to be flooded: one-way drainage ports on the sides and base of the sole plus a 3D air-mesh and neoprene upper. Pour water in and it exits through dedicated holes rather than pooling — near-instant drainage and quick drying. This is the cleanest drainage design of the shoes here.
• Sail Racing x On Cloud Regatta uses a perforated inner footbed feeding an outsole drainage system, with a non-absorbent antimicrobial mesh (30% recycled) upper so the fabric itself carries little water. Effective, and the antimicrobial mesh is a real quality-of-life detail for a shoe that spends its life wet.
• Gill Race Trainer uses a fast-release drainage system and moulded dispersion channels; the upper is a lightweight quick-drying construction. Comparable in intent to the Zhik.
• Dubarry, by design, does not self-drain like this — the whole point is the GORE-TEX bootie keeping water out. Its gaiter carries a drainage mesh at the base of the leg to release water that gets in over the top, but a fully immersed leather boot is a keep-dry system operating out of its envelope, not a drain-and-go shoe. That is the correct trade for offshore and the wrong one for an awash inshore foredeck.

For a Melges 40 cockpit and rail that ship water constantly inshore, the Zhik and Sail Racing drainage architectures are exactly the target; a leather boot is not.

Warmth, membranes and cold-water performance

This is where the boot archetype justifies itself, and the engineering splits into two waterproofing philosophies.

Neoprene (Zhik, Gill). A neoprene bootie is a wetsuit for the foot — it does not keep water out; it traps a thin layer the foot warms. Thickness is the lever, and Zhik exposes it directly: the 270 runs 4mm neoprene for cold-water warmth and durability; the 470 drops to 2mm neoprene over 1mm rubber to become the lightest high-cut boot Zhik makes, trading warmth for deck-feel and speed on and off (popular in foiling classes). Gill's Offshore Boot pairs a 3mm thermal neoprene inner with a three-layer XPLORE+ external gaiter and perforated neoprene to drain — a warmer, more protective bootie aimed at yacht rather than dinghy use. Neoprene's advantage is that being wet inside is fine; its limit is that it is warmth-by-thickness, and thickness costs mobility.

Laminated leather + GORE-TEX (Dubarry). Dubarry attacks the problem differently: keep the water out entirely. The Crosshaven laminates a GORE-TEX Duratherm membrane with 350g insulation and a thermally lined insole for genuine cold-and-wet warmth; the Ultima runs a GORE-TEX membrane in an uninsulated leather boot for milder conditions. GORE-TEX is a true waterproof-breathable laminate (an ePTFE membrane) — it blocks liquid ingress while passing vapour, so the foot stays dry from spray and from its own perspiration, which neoprene cannot do. This is the warmest, driest, most breathable of the systems for cold offshore work. The costs are weight, price and drainage: once water gets inside over the cuff, a waterproof boot is slow to clear it.

The material that makes Dubarry Dubarry: DryFast-DrySoft leather — a hydrophobic-treated hide the maker quotes as absorbing markedly less seawater and drying roughly 70% faster than standard leather, staying supple instead of going hard and cracking. Leather also breathes and moulds to the foot in a way synthetics do not, which is a real durability and comfort argument for long offshore use. Inshore, none of it matters.

Structure, last and weight — deck feel vs support

The stiff bit underfoot and the mass on the end of your leg are felt on every tack.

• Weight. Published: Sail Racing x On Cloud Regatta ~246g, Zhik ZKG ~300g per shoe. Dubarry's leather boots are the heaviest here (not published, but the leather-plus-membrane-plus-D-Chassis build makes it unavoidable). Zhik's 470 is engineered specifically to be the lightest high-cut boot (2mm neoprene, 1mm rubber). Swing weight compounds over a race full of tacks and manoeuvres — the lightest adequate option usually wins inshore.
• Support vs deck feel. The On Speedboard — a stiff propulsion plate — plus CloudTec pods give the Sail Racing shoe a structured, cushioned platform (running-derived, comfort-forward). At the other pole, Zhik's 470 is deliberately thin (1mm rubber) so you feel the boat — prized in high-load dinghy and foiling sailing where reading the platform through your feet matters. Dubarry's D-Chassis — a moulded RPU frame around heel and instep — sits at the support end, resisting pronation and side load for a heavier boot on a pitching offshore deck. On a Melges 40, most crew want the mid-ground: enough plate to edge a toerail and stand a long day, light enough to move, with a free ankle.
• Cut and ankle. Low-cut shoes (ZKG, Race Trainer, Cloud Regatta) maximise dorsiflexion for hiking and cockpit movement and shed the ankle collar's swing weight; the cost is zero lateral ankle support and less shin protection. Mid and high boots add support and warmth at the cost of mobility. For inshore Grand Prix the low-cut shoe is the near-universal choice; a rolled ankle is a real risk, but crews accept it for the mobility.

Durability and the non-marking caveat

Soft grippy rubber is a wear item — the same hysteresis that grips abrades. Expect a hard-raced inshore shoe's sole to be a consumable, and inspect the toe and heel scuff zones (where Zhik adds a skate-style cap and Dubarry/Gill add reinforcement). Two durability notes that matter on a Grand Prix boat:

• Genuinely non-marking or not. Every brand here claims non-marking, but soft compounds can transfer colour onto a pale non-skid or a white carbon cockpit under load and heat. A true non-marking formulation is a chemistry choice, not just a colour — worth confirming before a shoe lives on a show-finish deck.
• Cold-glazing. Natural and soft synthetic rubbers can harden and glaze with age and cold, quietly losing wet grip long before the tread wears out. None of the four publish a low-temperature grip figure, so an older boot that "looks fine" may not be — a real consideration for a boot that gets used a few cold weekends a year.

Dubarry's leather build is the genuine long-life durability story (resole-able, repairable, decade-plus with care); the synthetic racing shoes are lighter, cheaper to replace and treated more like consumables.

Value — read it per archetype, not across

Cross-archetype price comparison is meaningless (a leather offshore boot should cost more than a mesh shoe). Within each:

• Inshore racing shoe: Gill Race Trainer typically undercuts on price for a genuinely capable siped, self-draining shoe — the value play. The Zhik ZKG sits slightly above with the best-argued grip compound and drainage design. The Sail Racing x On Cloud Regatta is premium, and the On co-engineering (CloudTec, Speedboard, Missiongrip-derived compound, ~246g) is real content behind the price, not just branding.
• Cold-wet boot: Zhik (270/470) and Gill Offshore are the value-to-mid neoprene options; Dubarry is the premium leather/GORE-TEX benchmark whose cost buys materials and longevity, not markup.

Our picks by role

Footwear is role-driven, so we won't force a single winner:

• Inshore Melges 40 / Grand Prix deck shoe → the Sail Racing x On Cloud Regatta is the confident pick on genuine merit: ~246g, On-derived sticky compound over a real outsole drainage system, Speedboard structure and CloudTec cushioning for a long day in the cockpit, non-absorbent antimicrobial mesh. It is the most complete engineered inshore racing shoe of the four. The Zhik ZKG is the closest rival and the value-plus-drainage champion (roofer-refined ZK Sole, side-and-base drainage ports, ~300g); the Gill Race Trainer is the budget-capable pick.
• Cold, wet, offshore or delivery → Dubarry leather boots are the standout — GORE-TEX Duratherm warmth, DryFast-DrySoft leather, the D-Chassis frame. When it is genuinely cold, this is the right tool.
• Dinghy / foiling boot → Zhik 470 for lightest weight and maximum deck feel (2mm neoprene, 1mm rubber) or 270 when you want warmth and durability (4mm).

The takeaway

Sort by archetype first. Inshore, you want a light, hard-siped, fast-draining low-cut shoe with a soft non-marking compound and a free ankle — and on the published engineering the Sail Racing x On Cloud Regatta leads that group on merit, with Zhik's ZKG the value-and-drainage rival and Gill's Race Trainer the budget option. Offshore in the cold, the calculus flips to keep-dry: Dubarry's GORE-TEX leather boots are the benchmark, with Zhik and Gill neoprene boots the value alternatives. The honest unknown across all four is cold-temperature grip — none publish a hardness or low-temp figure, so glazing on an old sole is the failure mode to watch. Field notes to follow. See sailing gloves compared.

Our pick: Sail Racing (x On Cloud Regatta) for the Melges 40 inshore racing shoe — ~246g, On-derived compound and outsole drainage, Speedboard structure; Zhik ZKG when you want the same drain-and-grip logic at a keener price; and Dubarry GORE-TEX leather boots when the sailing turns cold, wet and offshore.
