Since the ultimate connection to the bike starts at the pedal, FOX has gone to great lengths to create the ultimate MTB shoe - the perfect blend of fit, comfort, and performance. The Union Boa is a high-performance shoe that will undoubtedly enhance your ride. The single-piece, welded, seamless upper reduces weight and provides a precise fit. The Dual BOA® Li2 Fit System offers millimeter-accurate adjustability through its dial closure, improving power transfer to the pedals while riding. The molded toe cap offers excellent protection against contact with rocks and stones. The high and low arch support can be customized individually, and the molded internal stiffening plate optimizes power transfer and comfort – on and off the bike. The Ultratrac™ rubber compound also provides outstanding durability and unparalleled grip. Compatible with all clipless pedals. Material: TPU/EVA/Rubber.
