I'm going Triathlon Sprint at LD and it is simply indispensable. Why waste 45s to his shoelaces when you spend hours in training and we spend a fortune in a gain of a few grams on his bike? In addition, the laces are "stylish" and maintaining and just perfect. This enables effective adjustment throughout the entire length of the foot. So I advise you even if you are not a triathlete! In short, very good product.
