On Cloud 6 Waterproof Review

Overview

The Cloud 6 Waterproof is On’s everyday sneaker with a membrane sewn in: the regular Cloud 6 platform, a tighter-woven upper, and a bootie-style collar that keeps rain out of a shoe designed for sidewalks. It suits travelers, commuters and trail-town resupply days. It is not a trail shoe, and the headline trade-off is plain: dry feet in a shower, hot feet everywhere else.

Performance

Weather protection. This is the shoe’s reason to exist, and it delivers. A WearTesters review describes it as the standard Cloud 6 with a waterproof membrane and a more tightly structured mesh added, and concludes that the upcharge, about $20 over the regular model, makes sense for anyone in a consistently rainy climate. A women’s reviewer on REI stepped into a bog and came out with dry feet. Owners in the Pacific Northwest buy it for exactly that reason. The enclosed bootie construction helps, since there is no gusset gap for puddle water to find. Like any low-cut shoe, it fails the moment water comes in over the collar.

Traction and ride. RunRepeat’s lab testing found the outsole rubber notably grippier than the standard Cloud 6’s, and rated traction high, with a stable, grounded ride and smooth heel-to-toe transitions. That grip is for wet pavement, boardwalks and groomed paths. The connected-pod outsole has no real lugs, so loose, muddy or steep ground is out of its depth. The Speedboard, a Nylon 6 plate, adds some forward roll and torsional structure, but the cushioning itself is rated moderate for shock absorption and energy return. RunRepeat’s testers said the shoe’s price had them expecting more softness for all-day wear.

Weight. On lists 296 g per shoe. RunRepeat’s scale read 318 g, and its testers marked the shoe as heavier than average for the category. Neither figure is ultralight. A typical trail runner with a membrane-free mesh upper comes in lighter and dries faster, which matters more on a long trail than the logo on the heel.

Breathability and drying. The weak point. RunRepeat lists poor breathability as a con, and owners describe the upper as stiff and prone to feeling damp inside, with the tongue stiffer than on other On shoes. Once water gets in, a membrane shoe holds it. Anyone planning multi-day wet walking should weigh that against the dry-on-day-one appeal.

Fit and durability. Fit splits owners. RunRepeat lists the shoe as slightly small. Some Zappos buyers report a tight instep and cramping even after sizing up half a size, while others find the regular size feels roomy, and a few say the upper breaks in after a few weeks of wear. Durability reports also diverge: RunRepeat’s lab rated it excellent, while one REI reviewer reported serious wear after roughly 90 days of regular use and was told it was normal wear and tear.

Pros & Cons

Pros

• Reliable waterproofing in an enclosed bootie that looks like a normal sneaker
• High-traction rubber outsole, grippier than the standard Cloud 6 in lab testing
• Stable, grounded ride with smooth transitions
• Easy on and off with no-tie laces
• Wipes clean after muddy days
• Orthotic friendly

Cons

• Poor breathability; warm and clammy in anything but cool, wet weather
• Heavier than average, with lab weight about 22 g above On’s claim
• Cushioning is moderate for the roughly $170–$180 asking price
• Stiff upper and tongue; fit runs small for many wearers
• Mixed durability reports from long-term owners

Who Should Buy This

The Cloud 6 Waterproof fits travelers, city commuters, and people on their feet all day in wet climates. It also suits hikers who want one shoe for town days, airport transit and drizzly bus-stop waits. It is a good pick for a cool-weather European trip or a rainy-season resupply stop.

Anyone planning real mileage should look elsewhere. Thru-hikers and fast-and-light backpackers are better served by a breathable trail runner that drains and dries, with deeper lugs and softer foam. The membrane here turns into a liability the first time a creek crossing tops the collar. Buyers with high insteps or wide feet should try these on before committing.

Verdict

The Cloud 6 Waterproof does what a rain-ready city sneaker should: it keeps feet dry, grips wet pavement, and looks tidy. It does not do enough on cushioning, weight or ventilation to justify the price for anyone shopping on trail merit. Buy it for travel and town, and leave it off the packing list for the trail.
