In reply to devonsi:
I've just started using the Instinct Lace-ups and love them.
As I'm still breaking thm in, I tend to stick with my Force Velcros for about 20 minutes while I warm up, then switch to the Instinct.
I'm quite flat footed so was wary of the shape being too agressive, but they seem to fit me fine in that respect. A bit more room in the toe knuckle area would be nice, but they are an all round great shoe, and well worth the money.
Given the height of the heel, you can probably go 1/2 a size higher than normal to give your toes more room, as the heel cups nicely.
