Scarpa Vapour S Review: A Flat, Sensitive Climbing Slipper With a Removable Strap
A practical look at the Scarpa Vapour S, a flat-profile climbing slipper with a soft M50 toe patch, a 3.5mm Vibram XS Grip 2 sole and a removable Nano Strap.
Introduction
The Vapour family has been one of Scarpa’s best selling lines worldwide, and it already covers a wide range of climbing needs. The Lace Up and the Velcro versions sit in that line as capable all-day shoes, well suited to hard traditional climbing and sport routes where solid edging matters most.
The Scarpa Vapour S adds something different. The S stands for slipper, and it is a slipper in the traditional sense, but with a twist: a strap across the instep. That single detail changes how the shoe behaves on the wall and how it fits into a quiver that may already include a stiffer, edgier pair.

The most important distinction sits underfoot. Both the Lace Up and the Velcro use Vibram XS-Edge, which delivers a stiff, durable sole with excellent longevity and edge support, at the cost of some tackiness and pasting ability. The Vapour S moves to Vibram XS Grip 2 instead, which shifts the priorities toward friction and feel.
Who This Shoe Is For
This is a shoe for climbers who want performance without the punishment that often comes with it. The flat sole and low volume toe box mean you do not have to knuckle the shoe up to wear it comfortably, while it still performs at a high level. That combination makes it realistic to keep on for a full session rather than pulling it off between attempts.
It also speaks directly to traditional gritstone climbing. The low toe profile torques into cracks well, and the softer toe patch means the shoe can be driven into constrictions and hooks without the discomfort that stiffer performance models can cause over a long day.
There is a clear audience here for climbers who loved classic flat, velcro-strapped grit shoes and want a modern equivalent. If that describes your preferences, the Vapour S is a natural place to look.
Main Strengths on Rock and in the Gym
Scarpa already makes plenty of downturned, sticky, soft shoes, so the Vapour S stands apart precisely because it does not follow that formula. It uses a flat sole with only a slight downturn at the toe, paired with a low volume toe box. Models like the Drago and the Chimera are brilliant and powerful right to the toe, but they need to be knuckled up to fit properly, which limits how long you can comfortably wear them.
The Vapour S avoids that trade-off. It holds its own on the modern style of bouldering indoors and outdoors, where a lot of pasting happens on volumes and features. The soft M50 toe patch sits like a hood over the top of the toe, so there is plenty of hooking power and crack performance without the pressure points that make some performance shoes harsh.

That combination showed up clearly on a small arete, where the shoe had to hold faith in friction on one foot while edging on the other. It handled both jobs at once, and what had felt exposed on previous attempts felt noticeably more secure.
Fit and the Nano Strap System
The Nano Strap is the detail that defines this shoe. It is removable and adjustable, and it is not there to force your heel back or generate pulling tension. Its job is simply to keep the shoe shut so the bungee does not open it up when you pull hard on the toe or the heel. That makes the shoe unusually versatile for something described as a slipper.
Adjustment is straightforward. If you are not filling the void and want a snugger fit, you pull the excess strap through and thread it back, which tightens the hold across the instep. Riders with narrower heels will likely need this. If you want a true slipper, you can fold the strap through, un-Velcro it and take it off completely.
That flexibility is genuinely useful. On a trip to Fontainebleau, the shoes were comfortable, edgy and smeary straight out of the box, and the strap could be pulled off entirely for running around spotting and then slipped back on for a quick session. For that kind of stop-start day, it is an ideal setup.
Sole, Midsole and Sensitivity
Underneath, the Vapour S uses a full length midsole combined with a tri-tension band that wraps around the shoe to help it keep its shape. Older shoes that saw heavy use could eventually lose their profile and go flat, and this construction is designed to help the shoe bounce back and keep performing over time.
The outsole itself is only 3.5mm thick, which is where the sensitivity comes from. Even with the midsole in place, the shoe still edges brilliantly, so you get feel and support in the same package rather than choosing between them.

Compared with the XS-Edge sole on the Lace Up and Velcro models, the XS Grip 2 compound prioritizes tackiness and pasting. The result is a shoe that reads the surface underfoot more clearly, which is exactly what gritstone and modern bouldering tend to reward.
Things to Consider Before Buying
Heel hooking is the one area where expectations should be calibrated. This is not an ideal heel hooking shoe. It does work very well for heel hooks and caused no issues in use, but if you get it tight it would likely perform better there. Climbers working harder boulder problems may need to size down for a tighter fit or look at a more aggressively shaped model instead.
It is also worth being clear about what this shoe is not. It is not a downturned, toe-focused power shoe, and it is not intended to replace a stiff edging machine for all-day trad or sport use. It offers a genuinely different feel, and the value comes from that difference rather than from out-performing every other shoe in the range.
Buying Advice
Buy the Vapour S if you want a flat, sensitive shoe that you can keep on all day and still trust near your limit. It suits traditional gritstone climbing, crack work, and the pasting-heavy style of modern indoor and outdoor bouldering, and it is a strong option for anyone who has been looking for a comfortable alternative to a knuckled-up performance shoe.
Pay attention to the strap during fitting. Climbers with narrower heels should plan to pull the excess through and thread it to take up the void, which makes a meaningful difference to how secure the shoe feels. If you prefer a true slipper, the strap comes off completely, so the same shoe covers both preferences.

The case for it is simple: comfort, padding and full confidence in the rubber, without the pain that usually accompanies a performance fit. If that sounds like the balance you have been chasing, this is a shoe worth trying on.
Conclusion
The Scarpa Vapour S fills a gap in the Vapour line that was nearly missing: a traditional style grit shoe with modern materials. It brings a flat sole, a low volume toe box, a soft M50 toe patch, a 3.5mm XS Grip 2 sole and a removable Nano Strap together into something you can wear comfortably for hours and still climb close to your best in. It will not hold you back, and you will not be in pain either.
