Unlike foot flippers, shinfinTM fins don’t give Adriana calf cramps or low back pain for her swim training and she can even use them for backstroke. This is because they give her a smooth swimming stroke which uses her thigh muscles, without cramping her calf muscles. What’s more, because they lift her thighs horizontal, that’s why they give her no low back pain too. So, overall they are much more comfortable for her.
