The Asics Gel Fujitrabuco 3 Neutral Trail Running Shoes were built for serious trail running with rugged uppers and aggressive, trail specific soles. Despite the rugged exterior, these shoes are really just big softies on the inside with Gel cushioning at the rear and forefoot which is set in Asics' soft and cushy Solyte midsoles. This makes them tough enough to handle rock covered, root strewn trails with ease, while still being easy on your feet when a quick three mile run turns into seven or eight. Since trails are rarely flat, the Gel Fujitrabucos feature a Heel Clutching System this locks your heels in place for a supportive fit. In addition to the secure heel pockets, the shoes are also fitted with internal elastic sleeves instead of traditional tongues, giving the shoes a sock like fit that is not only comfortable, but also helps reduce the chance of friction induced blisters.
