Shimano XC502 MTB Shoes Benefitting from trickle-down technology from Shimano's flagship S-PHYRE range, the XC502 MTB Shoes deliver performance at great value. The glass fibre reinforced sole efficiently transfers power through the pedals while the low stack height further increases efficiency and stabilises the foot. The shoes utilise Shimano's latest outsole technology, with ULTREAD compound maximising traction and durability. The upper is designed to improve support and aid ventilation, wrapping the foot for an almost customised fit and relief from potential hotspots. A velcro strap and BOA dial closure system allow plenty of room for adjustments, even mid-ride.
