Negative: They are thick and if your shoes are really really tight and theres no give in the material you MAY need to finesse your foot in. Happily these shoes are waterproof and fit perfectly. I used three large command hooks to hold this up. Very fun sounding. I love my Airpods but the left one felt a bit loose in my ear and I was concerned it might fall out whilst making my way across a busy ticket hall and get crushed underfoot. Love the volume control on the earcup, it works really well and has decent weight to it. With the big kids/little kids labels on sizes, I wasnt sure if the size 13/1 would be smaller and if so, by how much. You deff have to turn off the ads and to use certain xiaomi apps you need to give access but you can live without those apps honestly. Theres no problem with the bottom sole as it never has peeled off even after close to a year (which is really pushing it since I wear these every single day). I loved the design and colour, until my partner murdered them with the vacuum cleaner!
