The entire shoe is the Crocs plastic material, but these look like genuine sneakers, so when I tell people what they really are they are shocked. I did love the shoes Amazon just didn’t have in my regular size so I tried 1/2 size larger and they were way to big but I would recommend to anyone! Theres also a USB plug thats connected to the headphone. I have had the sense that the missing quality with the Bose was clarity. I highly recommend FitFlop if you have any trouble with your feet. I am the owner of Audio Technica M50x which are the best headphones I could own but these earbuds are obviously fake and should be reported. 5 shoe and purchased the 11-12 size, just for reference. Which makes for a difficulty in editing because its echoey due to this one. It looks very perfect on my marble counter. The outside sole is not too thick, which is fine for me.
