The Adidas adilette slide is the quintessential sports sandal on the market today. While all the brands have since tried to "luxe" up their slides (and in the process decrease their functionality), Adidas has kept the adilette as its always been. These are the only slides I've ever had that effortlessly give me the ability to get out of my cleats and into my sandals fast and comfortably. The sandal doesn't get the sock caught up when sliding your foot in and the upper keeps your foot snuggly inside. They are stylish as well. As far as sizing goes, I wear anywhere from a 10.5 to a 12 depending on brand and cut and I wear an 11 in these and they fit perfectly.
