I bought these shoes, as I often have problems with shoes that are completely closed and do not allow air into it. These shoes are great, they have holes in several places so that they are very breathable. I do not know what happens when it rains, as I previously was only in dry weather, but of summer shoes I expect not necessarily that they are 100% sealing. I like the shoes very well and they are very comfortable to wear! Therefore I a buy recommendation!
