has anyone bought a pair of clipless mtb shoes only to find them a wee bit tight? i understand that they'll stretch a bit..i just hope it'll be enough. the shoes are new sidi dominators, size 41 (small narrow feet). got them off ebay for cheap after months of shopping around. i need to replace my shimano road shoes.. sick and tired of walking around like a duck and falling on my ass.. wiped out the other week while walking on newly mopped floors in my building.
