I like the double elastic bands on top. Gave to my daughter who has very thin feet, and the said the toe loop rubbed skin raw. Traducido a terminos practicos, el bajeo no se siente en lo más mínimo, mas bien se escucha y suena congestionado. It is sturdy as far as holding the weight of the bike. Ich war sehr unzufrieden mit der Qualität der birkenstock Tongs der eine war voller weißer Kleber und sah auch schon nicht mehr neuwertig aus ??hätte für 65 Euro echt was besseres erwartet werde sie jetzt bei Birkenstock direkt bestellen If you do, be very careful as you can damage your ear-drum. Appearance and packaging are nice though. My only complaint is that if you have very high heeled shoes, they probably wont fit in these shelves unless you lay them sideways. Good for tuning out your coworkers Only complaint - straps to adjust are flimsy and hard to adjust.
