The size fits a bit small so persons should order a size up. The static noise I mentioned before is not audible to me for I havent been anywhere where it is so quiet you can hear a pin drop. And they ended up being the worst slide sandals I?ve ever owned & that includes the ones I?ve purchased at Walmart. And sure enough, about day three the strap no longer rubbed at all and the shoes fit perfectly! The key hooks have an unnecessary bulge at the end of it that acts as an obstruction when you put key rings on and off. I would buy this boat for any toddler/ kid. They have never fallen out with the silicone piece. This one can be set up in different configurations. They are a medium weight material and cool during warm days (90F). That was way too big, so I exchanged for a size 36, which their size chart says should fit a 5 to 5.
