These shoe covers have been seriously tested during some heavy rain and significant surface water events on my commute to work. Unfortunately, in these circumstances my feet get wet. As with another review, it seems that water wicking up the inside of the covers might be partly responsible. I'm wearing shoe covers 2 sizes larger so they fit over trainers. To be fair, my trainers need an upgrade, so the shoe covers might perform better with less porous shoes! Performance in less extreme weather is good - with dry and warm feet.
