The grip is just as good as any bike specific 510 shoe
I picked these shoes up as an alternative to ugly 510 mountain bike shoes. they're smaller, lower profile, not as hot, and they have the stealth rubber with a stiff insole that keeps your feet from bending over your pedals. i've ridden in these on four hour rides in moab and they worked incredibly. the grip is just as good as any bike specific 510 shoe. they just don't look as lame. i highlt recommend these shoes.
