Because regular foot fins are on your feet, they sink your hips down in the water when you swim. You can feel your chest dragging through the water. Foot flippers also make you bend your hips too much. This slopes your thighs down in the water and increases thigh drag. So they don’t help to improve kick technique. Worse, foot flippers reinforce a different kick to good swimming without fins.
Good squad swimmers have higher hips, kick with straighter hips and swim fast. However, you see many swimmers at the pool who kick with hips too low in the water and who bend their hips too much when they kick. Their legs slope down in the water, increasing drag. So their kick doesn’t feel so good and is low in power. This is a common problem which gets worse with foot flippers.
Your body remembers your higher hips, straighter hips and improved kick, even after you take off your shinfin
Now you can have fins for extra speed and have higher hips, straighter hips and improve kick technique!
