Fantastic training fins. My daughter is a wonderful swimmer at the age of six and has already completed the school age swimming programme for 5 - 16 year olds and is now in the first squad level. Squads often use fins and there was none provided in my daughter's size. After two hours web searching we came across your website and this perfect product going right down to accommodate smaller sizes. She wore them last night for the first time and loved them, easy to put on and take off. Great quality product made in Italy. Thank you.
