To account for the stretch I bought a medium (usually large) size so there isn't a ton of extra strap length. When I received it it just went through the loop. After 4 months of almost daily wear, the loop length has increased by almost 2 feet. Now I've got a ton of belts hanging from me. I really want this belt, but it's pretty much useless at the moment. That means I just paid ten dollars a month for a belt and now I have to buy a new one. Unsatisfied. I expected more from Nike.
