The Pure2Improve Shoe Weights are the perfect resistance training tool to add intensity to many exercises such as walking, running, gymnastics and general fitness training. The Comfort-Fit system keeps the Shoe Weights in place during exercise movements and because of the heel adjustable strap, it enables the weights to fit most shoe sizes, from ladies’ size 5 to men’s size 15. The heavy-duty rubber strap wraps securely around the bottom of the shoe, with a strong Nylon mesh for high visibility. The pack contains 2x 0.75kg weights, for each foot.
