I've been very happy with my Endura neoprene shoe covers. I had several previous- Peal Izumi, Garneau - they were flimsy and their bottoms were easily torn. The Endura are warmer, really waterproof, and lasting much longer. I think all shoe covers eventually tear at the bottom- it's the shoe cleats that do it, but after several years of use, the Endura are still quite usable. I am thinking I will have to replace them after this year, and won't hesitate to by them again (though I think their model lineup has changed?)
