These insoles are really super. They keep you warm and comfortable. Did for my Stifel ordered which have a really high heel. By deposits they are now not only warm but also comfortable to wear. The feet do not hurt and if it is still too hot the sweat is absorbed without slipping or unpleasant odors. One size bigger would the shoes, however, otherwise there could already be a bit tight. For cold winter days I can only recommend this soles.
