MTB shoes with light and precise fit. The shoe is perfect for any adventure on Mountaibiken, where it provides a good fit and really good protection. The shoe uses 2 BOA Li2 buckles which can be adjusted very precisely so that they fit your foot perfectly. In the sole, there is an internal reinforcement plate which provides good protection, but also a high performance by making the sole stiffer. This means that more of the power produced is transferred to the pedals. The shoe is also reinforced in the toe area to provide greater protection against impact. The outsole is produced with Fox's Ultratac compound and a specially developed tread pattern, which gives a very good grip and good durability. The shoe is compatible with all the major pedal suppliers.
