I wear a 6 1/2 to 7 size, so I always choose 7 when ordering online and these fit me perfectly as you can see! Beautifully made sandals, but theyre slimmer than all the other Olukai sandals and shoes I own. This product is solid and won?t break easily like other plastic stands that I have used in the past. Sound quality is great, average noise cancellation comparing with other models which have active noise cancellations. The cable is replacable and works fine though a bit tangle-prone. The color of these are pretty awesome too, especially seeing as Green is my favorite color. It forgets to mention that there must be a centre piece as well on those roof rails. It isnt a 100% fit for my ears, though I have changed the size of the bud tips. The heal is supported with a quarter inch insert and an additional foam I get from the shoe itself. Taking advice from other reviewers I ordered a half size up.
