Coming out of Gaerne Fastback Endurance boots which, even after extensive break in, never fit my feet comfortably. The SIDI's fit me really well and stay comfortable even after hours on the pegs (My longest ride was about 3 hours but most of it standing). The narrower heel holds my ankle and foot snugly but comfortably. The roomier toe accommodates my wider forefeet and also allows some foot expansion during a long ride. Design is just right, lots of protection but incorporated without making the boots big, heavy and clunky. That makes these really confidence inspiring on the bike as you get good feel for the controls, without sacrificing the protection that you're wearing these for. I don't walk much in my riding boots but did go a short distance on a trail wearing the SIDI's. They aren't uncomfortable but if you plan on doing any more than minimal walking around, bring a pair of walking shoes with you. The materials seem excellent and look like they will last. Personally, I don't see much downside to the glued soles (vs. a stitched on sole) as by the time they wear out, I'll likely be ready for new boots anyway. While everything about these boots seems pretty first class, only time will tell if they will provide longevity. Out of the box, my left boot had a sharp staple protruding enough to go all the way through the insole and poke my heel. An easy fix but something to watch out for. Overall, after a week of riding in these, I am very happy. The X Power SC's provide great protection while not being ungainly to wear. They fit super comfortably and have (other than the staple) since they came out of the box. At $100 off, these seem like an honest bargain.
