Many customers have stated that the shoes be very large. This I can not confirm. I normally Schuhgöße 44 and therefore the shoes ordered in 43. Result: too small. Reordering in size 44 fits perfectly. The shoes have a very soft sole. Long walks on stones and rocks, they are unlikely to endure. For the sole is very grippy and perfect for slippery surface in the water. Are just aqua shoes and no hiking boots.
