Soft to the touch and fun to use. These are the silicone fins from BornToSwim®. BornToSwim have tried them on their own kids and to say the least, they love to splash around with them and do not want to take them off. The ideal short length, anti-skid bottom, and soft material make the fins a perfect addition to your child's swimming time. Since the fins are short and highly flexible, they do not put extra strain on your child's developing ankle, therefore making them kid safe. Have your kids put the fins on their hands like paddles instead of their feet and look at them under water while their kick. This will help them get used to having their head in the water while swimming.
