I am 69 yr old. Was worried fins were 3x more than other fins I own. First workout was incredible. Could feel big difference in the very first lap in my muscles. Think it is weight and design of fins that accelerates muscle stress. Cut my swimming from 45 mins to thirty and thirty was tough to complete. Well worth the investment. Highly recommend! Never written a review before.

I’ve been a masters swimmer for almost 20 years now. These are the best and most durable fins I’ve ever had. These put the Speedo fins to shame.

I love that these fins are soft and streamlined. However the sizing is wonky for American sizes. First I ordered a size 8, which is my American shoe size. The fins are marked 39/40, which is American size 9 and 10 so they're way too big, Then I ordered the size 6-7, fins are marked 37/38 so I hoped these would fit since I wear a size 38 in Dansko clogs and other European shoes. These fins are more like an American 7. If you're a size 8 US, you have to choose between fins falling off at the heel and being way too big in the foot (so you lose the power of the fin) or the fins being a half size too small and your toes are a bit cramped. Arena, how about an adjustable heel strap? Or how about making a true size 38 for US size 8 feet?

no tengo nada que decir respecto al producto en si, funciona bien, son de buen material, son cortas para trabajar potencia de la patada en el agua y se acomodan bien. Mi nico problema fue el delivery, donde la empresa envi de forma errnea el pedido a otra direccin, lo cual fue bastante engorroso de resolver.
