After about a year Power Grips IMO surpass alternatives. Toe clips and my Bata Bikers worked fine 'till cleats became necessary. Finding 12EEE shoes was an ordeal, but finally located a pair of Sidi. The stiff sole split after a few years. Sidi's rep made me a 'deal' on their 'Genius' model in replacement. The ratchet mechanism suffered durability similar to the original's soles. So bravo that persistence has rewarded Sidi per praise elsewhere for their Dominator. The Genius still serve though a velcro strap from Home Depot replaced the failed mechanism that I removed.
About a year ago I lost my balance while getting under way. It kept me from riding nearly two months. OK I'm a klutz. But the Look Pedals / cleated Sidi Genius shoes are for my vintage Nishiki and the trainer. My ancient Bata Bikers are on borrowed time. I'm scoping out possibilities, confident that compatible shoe awaits discovery.
