Our first ROCLITE shoe to feature Graphene in both the rubber and foam has been designed to take runners beyond their distance limits – no matter what the terrain. Equally happy on-trail or off-trail, the super-durable 6mm GRAPHENE-GRIP lugs bite and hold across all ground, from hard rock to soft bog. The G-FLY Graphene cushioned foam provides 25% greater energy return that lasts for longer, while a super-strong new mesh upper, flexible rockplate and reinforced toe bumper all keep feet protected. An evolution of the ROCLITE G 275, with improved bounce, cushioning and protection for racking up bigger miles.
