I was given some lovely toe overshoes. These are great for chilly, damp spring days, just to take the edge off, when full overshoes would be too hot. These ones I was given had a Velcro strap under the foot. The strap did interfere with my SPD cleats a bit, but I could still clip in. They make a noticeable difference to the temperature of the toe area. How do I know this, well the Velcor strap came undone on one overshoe and it fell off, never to be seen again. But when I did finally notice I was missing one, I released that one foot was much warmer than the other!
