The Sportwax seals the shoes off nicely, but unfortunately no foolproof instructions are supplied. First: wax contracts under heat into the leather. As is generally discouraged Yes, deliver to the offender previously in the oven (especially GoreTex membranes are not particularly like), remains the only Kalteinreiben. Then the shoes are watching not only little pretty, but enormously sticky and attract dirt and dust at each. Water, however, will roll off nicely!
The way out: Shoes for waxing in the blazing sun and make contact on a regular basis in order to provide all parties. The surface is really nice again and the sticky film disappears.
