I bought these for my daughter, sight unseen, for our dive trip to Oahu. I did plenty of research and these seemed like a good fin at a good price. Indeed, are excellent fins for the price. I have Scubapro fins that are very stiff and frankly are not friendly on the ankles...so I didn't want that for my daughter. These fins were perfect. They are pretty long fins, though not as long as those you see for spear-fishermen. The length combined with the overall flexibility of the fin made them perfect for a comfortable experience. My daughter said she never had any pain and that they were a very nice fit. Highly recommend. Thinking about getting a pair for myself!
