In triathlons, any little advantage, no matter how small it seems, adds up to big savings in the long haul. Every detail of Bontrager's RXL Hilo WSD Triathlon shoes are made to make you more efficient, period. The main strap is huge, no fussing around, just slam your feet in there and flip the strap— done, even while on the bike. The heel loop is huge, so even with wet hands, there's no fumbling trying to get your finger in or out. The microfiber uppers with flow-through mesh panels combined with perforated ergonomic inForm footbeds dry quickly and give you airy comfort on the hottest days. Bontrager's super-light carbon soles offer the ultimate in power transfer and support, too. Say hello to new PRs.
