[This review was collected as part of a promotion.] The product info says it adjusts to fit all ankle sizes, but that was not true for me because my ankles are so small that I couldn’t get a snug fit around my ankle, even at the tightest fitting and even while wearing socks. Regardless of my personal experience, this resistance band is very well made. Soft cushioning on the inside makes the band comfortable even if you don’t wear socks before putting it on, and the Velcro closing seems strong enough to keep it closed. This only came as a one-pack, so you’ll need to buy another one if you want to do to leg-to-leg strength or muscle improving exercises, otherwise, you’ll have to attach one end to a cable machine.
