They are very comfortable at this point and the strap over my foot feels snug, soft and fitted to the point that they are not given a thought about as i trek threw my day. Finding slippers in Japan was near impossible. These fit as expected and have held up very well for my wild toddler playing in them. Las pantunflas están muy bonitas! Buckle and quality Audio quality is ok on bluetooth, slightly better with provided 3. They do have a nice sound but for some reason when I plug them into my cell phone and listen to YouTube videos there are many pops and clicks that result -- that didnt happen with my cheap 5 dollar headphones! Except the device doesnt tell you it is in pairing mode with audio or when it connects. This is what COVID could do to your brain. I bought these speakers so I could use them in party mode to have stereo speakers for listening to music.
