I bought this same boot last summer to use this past season. Best fitting boot I have found yet! I wear a 21.5--could use a true 21-- . I am about 90ish pounds and have found the 95 flex works great for me. I've gone through a few different models of Junior race boots with mediocre results as far as performance, likely due to them still being a tad too wide despite what their last measurements state. This boot is perfection for me. It had been suggested by a bootfitter in Oregon ( I live in Arizona ) I spent a few hours calling race shops around the country to get opinions on my boot needs, and this gentleman mentioned the Club Sport, which he said they did not sell anymore due to some issue regarding the flex inconsistency, or something like that. Not to be deterred I then tracked down a pair. I'd like to buy a back-up if anyone has my size available!!!!!!!!!
