For daily shoes, you only need just above 1,000mmH2O to keep your feet dry in the most of the situations. And a higher waterproof rating comes at the cost of reduced breathability, which can lead to sweaty feet and discomfort. Sticking with 1,000mmH2O, Cestro strikes the perfect balance between waterproofness and breathability.
