Their shoes almost always fit well & the Rime which comes in an impressive array of 15 sizes (40 to 50 with half sizes between 42 & 46) is no exception. Its also quite light for a shoe with a Vibram outsole Â- our samples weigh just 411g each The Rime is said to be a ‘7Â’ on SpecializedÂ’s pedaling efficiency index scale where their race-level S-Works & S-Works EVO shoes measure 10. We found the nylon sole offered a great balance of on-the-bike stiffness (enough to keep feet happy & without fatigue after four-plus hours of pedaling) & off-the-bike performance (soft enough to hike in comfortably without hotspots on your heels or elsewhere). One of the features that conspires to produce the ‘fitnessÂ’ look is actually appreciated both on the bike & trail Â- the foam cushioned heel pad. We walked away uninjured from a tripod landing off a sketchy drop when wearing the Rimes; with an ultra rigid race shoe we probably wouldnt have been so lucky. Though super-supple light & comfortable the RimeÂ’s synthetic upper has proven very durable over the course of our four-month test period. It does stretch however which aids comfort but prompts fine-tuning of the closure a couple times during each ride. The two forefoot Velcro straps are accompanied by BoaÂ’s new S2 dial closure which winds both ways rather than having a separate release function. It uses stainless steel cable & is mounted on the forefoot strap rather than the side of the shoe keeping it out of harms way.
