Because I wore the boots after receipt in mud and rain, I could not very well send them back yes, although I would have done the most. The shoe is waterproof (1 Star). It is easy to dress and undress (second star). Warm feet you only if you run hard. It runs longer, you start to sweat it, resulting in wet feet. And the socks and the thermal shoe only once wet, are also the feet no longer warm. Despite the thermal inner boot can be felt behind the crossing point "rubber shoe Polyester shaft". The thermal inner boot can take out as it is but attached with Velcro, this is not so simple. To dry the liner has to be taken out, otherwise it takes forever until you can wear the shoes again. On the heating of the liner requires more than 6 hours to dry, if additionally paper is gorged. Can turn to the left to the liner not. Because of the surface fastener can not bear no inside shoe to shoe.
