Not too bad....but they are prettty tight. I got them online for $30 and I wear size 10.5 street shoes, so i got a 43. After trying them on I would say a 44 would be better for a 10.5 unless you like them very tight.
Its a good pack, but the waist belt leaves something to be desired. Under heavy loads it chaffed and eventually rubbed the skin off my hip bones, but besides the permanent scares on my hips it really is a great pack.
