these fins are made of a hard plastic and dont bend easily or glide easily thru the water, I did not care for them, I would recommend getting a softer rubber fin. It was harder to kick with these.
Used them in Mexico and they were fantastic! For the price paid they were a bargain and much better than the finn's supplied by tour boat operators. Buy'em and take'em with you - you'll be glad you did!
Really nice fins for the price. The fins are being used for recreational swimming for fitness purposes and they are great.
I use this product specificly for swim workouts on leg days, I wear a 10.5 running shoe and purchased the x-lrg fins with a pair of water sox. the fins fit perfectly, for the money there worth the investment.
We used these snorkeling in mexico and had no problems at all. It's nice to have the slip on back. Everything was great.
