Sommerschuh deluxe

I looked at my shoes a few years ago in a sports shop.
This shoe is designed specifically for sailing: the sole is very slippery and the Upper extremely breathable.
The sole is the highlight of the shoe: the ingenious membrane water can get out of the shoe, but no beach sand in the shoes inside (at least not by the sole).
For hot summer days the shoe is ideal because it is permeable to air.
Its round shape provides a very comfortable wear.
By the white sole, the entire foot is very much smaller - a shoe size 40 looks like a size 37th
