I really like that these are not actually designed to be inserted into the ear. These shoes are stylish AND comfortable! The sound quality is amazing, the design is sleek and modern, and the fully customizable RGB lights are so freaking awesome! My foot is 8 1/2 " long, regular arch and width. This was a gift for my husband, to replace his previous deer stag ones, that were about 15 years old. These are a little on the large side from what I was expecting (I ordered a 7 and a 6 probably would have done it) but the strap holds them on. These fit just snug in my ears and still am able to fit my desktop over head closed ear g933s and listen to music while gaming or whatnot. Well made and comfy sandals. These work really well for water aerobics which is what I needed them for. Needed additional hooks in the bathroom for the kids.
