Quick-release buckles aid in fin removal and replacement. Modifications Pull tabs added to heel straps aid with moving the strap over the heel without readjusting it. If a full-foot fin is too large for a child this year, a sock or tropical dive bootie may fill the gap as he or she grows. Usage Hints ScubaLab tests clearly demonstrate that the ability of a diver to kick correctly is more important than which fin is used. For most fins, a slow, strong kick from the hips with pointed toes and a minimum of leg bending is most efficient.
Fins only work under water.
When snorkeling, the fins should stay there as much as possible. Most of these fins are available in both full foot and adjustable models. For snorkeling, flexible, light, smaller fins are better. Many such fins are available so selection will be based on a comfortable fit with what is available locally. Because they have the greatest impact on your safety while diving, regulators must receive your most serious and detailed consideration.
