Slipper is not leather and is only fair quality for Daniel Green. Covered and added my own knobs. Ich hoffe, dass das Material auch längere Zeit durchhält und nicht nach ein paar Monaten schlapp macht, vor allem im Bereich der 2Knickkanten" - aber das bleibt abzuwarten. No es mi primer producto Bose y espero no sea el último Now after using my Hoplynn EVERYDAY (while cleaning and exercising) my waist has gotten smaller, down to a 32in 😃. My flat flip flops caused issues. Okay, not actually "glued" like you and I would think, it has some glue and was partially stuck on the top of the shoe. Bit on the small side but ok A tip is to be sure you have good wireless connection near the speakers too. These fit perfectly, they feel snug and cozy but not too tight.
