Hi Dianne,
Our shoes are breathable thanks to a special material called Dyma-tex that we developed ourselves. It contains millions of pores large enough for the heat and moisture from your feet to escape, but small enough to prevent outside water from creeping in!
Vessis are way more breathable (and lightweight) than traditional waterproof footwear options - like rubber boots. That being said, waterproof shoes will always be a little less breathable than normal shoes. We thought it was nice to have another option rather than wearing heavy, clunky rain boots all the time.
We will be sure to share your feedback with our product team as we're always looking for ways to improve.
“These were an ad on to get free shipping but what a pleasant surprise when they arrived. They fit great (no slouching) but are light and very breathable. Love them!!”
