I have read a number of threads about overshoes and there is one general theme. They are not made to last. I use spd cleats which sit more or less inside the sole of the shoes as opposed to the 'road' SL cleats which sit more or less proud of the sole, so walking before, during (cafe stops) and after quickly damages the material on the sole of the overshoe. I have tried a number of types and all tend to only last 1 winter season. I don't want to pay a fortune, but if a manufacturer would come up with an overshoe with a very hard wearing base it would be best seller.
