I picked up a pair of boots a few months ago and they seem to fit well without any work which makes me a little nervous. I measured 0.76 inches pretty much exactly from my heel to the back of the shell with my toes touching the front of the boot. Does this sound like it's too much room? I can exchange for the next shell size down (25.5 from 26) but the liner is already pretty damn tight. The boot in question is a Head Raptor Supershape.
