Been wearing them for 4 years and they are still perfect. Not too hot, toasty but not sweaty feet, NOT clunky, and I can ride in them.
The hus' knew I wanted them and bought me a pair, but in the wrong size - 9. I should sell them, they're just sitting around in the box.
But either way, I can go through regular rubber boots in a season or 2, I've used these 3 seasons a year for years.
