Reima mid-season boots

Reima Hiivin mid-season shoes. Purchased new and worn by one child for one season. Technically and externally, they are in very good condition. However, the textile material on the upper part inside the boots is somewhat faded and "dirty." The boots have, of course, been carefully cleaned and maintained, but this is due to active wear in kindergarten. Those white dots on the black sole part, in my opinion, have come from washing the sole, from the white part of the sole.
