They are OK and fit well at first just walking around my house trying them on.  But, after putting them to use, I probably should have returned them.  The sock lining is very slippery and unless you're willing to go without socks (ugh...no...why) you might find yourself sliding around in them pretty bad.  I have a hard time doing anything in these at the gym besides strictly weights.  When I switch to cardio my toes are finding themselves jammed up at the front from my foot sliding on the insole.  I gave it a try without socks...magically no problem  Normally, I'd think this called for a smaller size, but if i had gone any smaller, my toes would have been smashed just standing still.
