As part of my "in case it rains" gear, I have waterproof jacket, waterproof trousers and waterproof overshoes.
The first time I used them I had the "brilliant" idea to tuck the trousers into the overshoes, with the result of pouring all the rainwater directly into my shoes. What a miserable day it was.
Last time, remembering the previous experience, I have fastened the trousers Velcro straps around the overshoes making sure that the overshoes were under the trousers. At the end of the rainy day my socks, shoes and feet were nevertheless drenched in water.
Am I missing something in the way I should use overshoes, or is it simply unrealistic to have really waterproof overshoes?
I use cleats, leather mountain-bike shoes and when the above happened I rode about 6 hours, the first 4 under the rain, on mostly paved roads and some white roads.
