I had a lovely ride out on Sunday, in the pouring rain. My winter boots (Shimano MW81's) are very good at keeping my feet warm, but judging by the amount of water I poured out of them at the end of the ride, they are not waterproof. My feet didn't get cold, so I'm not too bothered about that aspect, but th eboots have taken until today to dry out, a PITA when I want them for commuting duties. Can anyone recommend a decent set of waterproof overshoes please? Need to work with MTB (SPD) cleats. Ta.
