We regret now not having bought this long ago. This is my second pair and they are the best flip flops I have ever had. Waist size a 28/29. Thats slick - thats an idea by a company who grew up making headsets for wireless phones. If youre using it to just charge it on the ps4 or sync a controller to it, works fine. Just seems to me the difference between these £7 Jib ones and the old £12 Inkd ones I used to get is enormous. The medium is pretty big around the armpits but the rest fits great. They are way softer and flimsy than the originals. -It has a very comfortable heel which makes the shoe comfortable and elegant. The silicone is very thick and poorly cut/sized.
