So my friends gave me a pair of diadora spd-sl shoes for my birthday and apparently they are sized differently from shimanos in that their 43's are at least an inch longer than that of their japanese counterpart. I was wondering if anyone had tried using insoles to at least mitigate some of the annoying play that comes with pedaling in shoes that are too big? I understand that's not the main purpose of insoles, but would they help and are there any cycling specific insoles out there? I have found Specialized to make some, any other options? thanks in advance
