The Sidi Buvel Mountain Shoe features a two-way caliper buckle for easy on-the-fly bike adjustment offering slight incremental loosening and tensioning. Two velcro straps are also located lower on the shoe for easy forefoot adjustment. Towards the rear of the shoe you will find an external, reinforced heel cup that offers superior fit and power transfer while also offering a more robust design that won’t break down over time. Just like any other Sidi, the Buvel is designed with Sidi’s known quality and construction. With bold new color offerings and an array of different sizes, these shoes are sure to look good and feel even better out on the trail.
