I swim much farther with less effort and soreness in my upper body.
These are great for snorkeling. They are small and light weight so they fit into a carry-on bag for your trip to the tropics. Half sizes need the next size up to feel comfortable.
I can tell the fins are improving my kick and making me a stronger swimmer.
I use the product for swimming on a team and they are really comfortable and fit well. They really do help the proper kick motion and position in backstroke and freestyle and butterfly .
Not quite as fast as big flippers, but much easier to carry around.
it was hard to decide which size to get as my size is 71/2 or an 8 womens. I got the xs and they are a little hard to put on but fit great. I love how light and comfortable they are! my whole swim group uses these.
