Bought shoes expecting them to work as advertised, instead the waterproofing lasted for only a few wears and now is as prone to soggy shoes in the slightest of groundwater as other five-fingers with the added problem that these don't breathe like others and even a gentle walk somewhere can make the shoes wet inside from perspiration. No idea why or how the waterproofing failed - no rough treatment or reasonable explanation, just gone within a month or so with maybe less than ten wears. The thicker sole doesn't have as good flexibility as other five-fingers and sensory feedback is lacking too.
