The Fuji Attack 4, now boasting a Solyte midsole, is a lightweight trail shoe with an aggressive outsole pattern to cater for all types of trail use. It is low profile, has a rearfoot GEL unit and forefoot rock protection plate. Lasting provides inner platform comfort while a Trusstic gives midfoot support. A full ground contact outsole combined with a new upper incorporating discreet Eyestay lacing technology result in a shoe that is both stable and incredibly comfortable. Pronation is how a runner's foot rolls laterally between footfall and toe-off. Underpronation is when the foot rolls outwards, overpronation is when it rolls inwards, and a neutral pattern is when little rolling occurs. Matching a shoe's properties with the runner's running style will increase comfort, running efficiency, and contribute to decreasing the risk of injury.
