Im wondering if the long wooden part (Part K) is not uniformly cut. No bowing or any wobbling at all a really brilliant product. I had researched by visiting camping supply stores, auto stores, Wal-Mart and its competitors. Absolutely annoying. But its a stiff and heavy slipper. its not as much about length as it is width. Le ho provate anche in chiamata e l’audio è nitido sia per chi chiama sia per chi riceve. So beautiful I placed it on my door but I removed the hook These shoes somehow look more expensive in the illustration. Comfort - this is where i am really impressed .
