Review: Arena Fins - A little bit pricey when it comes to fins but they are worth the money. Perfect for a competitive swimmer. This is our second pair. The first pair ran a little bit big. So keep that mind and mind when purchasing. They are super easy to use in the water and makes sure legs work a little bit harder than traditional fins. Comfortable and not to rough.
Review: Excellent - Excellent quality as usual!!! Fits perfectly, my son loves them!
