I recently ran Zombie Apocalypse 5k (Run For Your Lives) AMAZING! These shoes totally rocked him! However, I had to pre-mod the TERRIBLE strap and minimal Velcro that came with it. Basically only about an inch and a half of velcro material so it's pretty horrible to tighten. Easy to attach with spare velcro, gorilla glue, and scissors (to cut the new velcro to the perfect size to fit on the strap) when 5/5 hand down comfort is an issue. Belt problems -1 point
