This pull buoy is specifically designed for practising swimrun. Its two side straps can easily be adjusted to the leg and placed on the outside while running. When it’s time to get into the water, simply turn the buoy so it fits between your legs, to keep them from sinking. The perfect solution to compensate for the loss of speed caused by wearing shoes. Thanks to its great buoyancy, it keeps your hips on the surface and your lower trunk stable.
