Overview
For all our S/LAB ULTRA 3 lovers, we kept what makes this shoe a bestseller comfort fit and long-distance ride but updated the upper to reduce the weight by 10%. The new Matryx® mesh is breathable and ultra-resistant for a lasting sock-like fit. The midsole still offers great cushioning, while the Contagrip® outsole powers through the kilometers.
