The shoes are cozy, warm and cuddly and slip is not as strong as it was feared the absence of ABS-studs on slippery surfaces. The brown plastic tape, as already described by others, useless and purely decorative. After a short gestation period, it slips through the tabs and the maintenance of the shoes on the heel is lost making them slide down while running over the heel. By replacing these bands by brown or black laces (see User photo), you can adjust the hold itself and he retained after knotting the laces too. For durability, I can after 3 weeks use not say anything, but I hope they are not as sensitive as criticized in some reviews. So far I can in any case give a buy recommendation and awarded 4 out of 5 points.
Addendum: After three months of moderate use (morning, evening and during the weekend) I must now, however, two points pull off due to lack of durability. The lining gradually distributed in the form of 1cm large dust bunnies in the apartment, which would, however, still to get over. More serious, however, is that the stitching on the heel dissolve now. This is after three months then for that price a bit early. One year I would have been desired. But it proves true just yet again: who buys cheap, buys twice. Too bad!
