Hi all, I am rather new to the motorcycle scene as I just purchased my cbr250r and am learning the tricks of the trade. I was able to snag a once worn pair of Alpinestar smx 5's which are a mere half size, if that, too big. Keen to hear what you guys do in order to tighten them up just that extra bit? In my Army boots we have extra soles for our heels, but I'm not entirely sure that would always work best in all situations. Cheers!
