we had the boots was unfortunately turned out very rarely because of the winter here to mmild but overall had our daughter warm, not sweaty feet which was always very important to us. They are processed robust and keep water and mud also from. The sole prevents slipping and allows you to also run well. next winter we will buy again which. The only drawback is that you can not remove the soles inside the shoes I have ever aired out and they were never damp from the inside.
