You don’t have to slap your feet into the water as fast as freestyle swimming. You mainly rely on swinging your thighs up and down to let your feet hit the water (never use your ankles to slap your feet into the water, as this will easily cause cramps). It is recommended that novices start every second. Familiar with the speed of the left and right feet.
When walking ashore in shallow water with your soles on, you may feel a little strenuous. In this case, you can turn your back and walk ashore backwards, and everything will become a breeze.
