I love these velcro straps. I used them to cinch in my coulottes at the knee before riding my bike to work. I'd like to use them on the lower calf, but they slipped off. I plan to remedy this by sewing some strips cut from a latex glove to the inner surface so that they won't slip off. These are exactly what I needed to be able to ride to work without my clothes getting caught in my bike chain.
