I wanted a pair of short fins for exercise and transportation purposes. I am not an athlete and I use them in the sea, so I cannot be completely objective about their use. I chose these specifically because I really liked the design. In terms of positives, the color and design (usually all these fins are blue, black, yellow - these are different), the anatomical foot pocket, and the result during use (my legs actually feel exercised). On the negative side, they are quite heavy (honestly, I didn't expect them to be so heavy), it is difficult to put them on and take them off (unless your feet are wet, it is practically impossible), and worst of all, the foot pocket is very hard and tight, which results in injuring the ankle area. Of course, it doesn't bother me when I swim, but I get hurt when putting them on and taking them off. Overall, I give them 4 stars (otherwise I would give 3) because the design and the result of their use outweigh the negatives.
