That?s almost a decade of beating the crap out of them, getting tossed around, and suffering dirty feet days on the trails with the Jeep! Waste of money! The opening goes far enough toward the toe to allow for the occasional swelling of the tops of my feet. It does not and that makes for a tight fit. I will see but my ride buddy suggested a more expensive attachment because of tab concerns and the amount of money we already have invested in computers and light why not he told me. I use it to hold yarn for crochet projects. From audio setting perspective, it only has 3 options - Bass, Center Channel, and Trebel. Extremely comfortable and well made shoes! Please do NOT buy these Skechers. I take them with me when I travel or stay all night with my kids.
