Mit diesen Schuhen meisterte ich neun Stunden Stehen bei der Arbeit ohne Probleme. A bit awkward to assemble and came missing a bolt but Thule shipped the bolt within 5 days. Again DO NOT BUY THIS ITEM! This also means that I dont have to keep switching batteries, which I consider a win. Nice and lightweight. But overall we loved them! Ich habe nicht genau gemessen wie lange aber auf mindestens 15h kommt er garantiert. Easy to pop into wardrobe but you can easily see and access shoes. What’s odd other reviews say it does. 5 to fill the gap.
