Upper: Water drainage system releases excess moisture. Padded tongue and heel collar for added comfort. Lightweight and breathable mesh upper with synthetic overlays for added support and style.
Midsole: Solyte midsole material is a lighter weight midsole compound than EVA or SpEVA. The Trusstic System reduces the weight of the sole unit while retaining the structural integrity of the shoe. Heel GEL cushioning system attenuates shock during impact for a smoother transition to the midstance. Removable, perforated EVA sockliner provides lightweight cushioning and improves moisture drainage.
Outsole: AHAR (ASICS High Abrasion Rubber) is placed in high-wear areas for improved durability. Aggressive trail lugs provide plenty of traction on off-road surfacesRunner's World Best Update.
"The Fuji Racer, with its thin, flexible plate under the forefoot, provides considerable protection from sharp, off-road obstacles. That said, the forefoot is exceedingly firm, as evidenced by our Shoe Lab data. On the opposite end of the shoe, the Racer’s heel offers sufficient cushioning and more than enough comfort. ‘The heel fit was excellent without needing to use the extra lacing holes that many of us women often need to,’ says Melanie Marinaccio, a wear-tester from Reading. Some testers pointed out that the drainage holes, a smart way to move loads of water out of the shoe, let in water. ‘On wet days, it didn’t take long for the bottom of your feet to get wet,’ says Pierre Sirois of East Lansing. Bottom line: for lightweight efficient runners who want to run fast on dry trails. "
