Designed to offer increased comfort and performance, the Salomon S/Pro 100 GW boots combine easy step-in, customization options, and a seamless liner so every day on the mountain is a rad experience. A 100mm last fits a wide variety of foot sizes with ease, while a 100 flex offers response and stability while still being easy to manipulate. A Custom Shell HD and My Custom 3D seamless Perf liner can be customized in minutes to offer a precise feel, giving a perfect fit for staying out on the slopes from bell to bell. This is the medium volume (MV) version.
