Scholls do not come in half sizes. /Users/masoneinhorn/Desktop/IMG_5023. locate your studs before you drill. I may need to cut off the last row to make it fit. But I’m sure as I wear them more-it will be easy to get them fastened. Since I listen to headphones about 20+ hours a week at work, it seemed like a worthy investment. The shelf is sturdy and well designed. I definitely recommend these for comfort, fit and wear-ability without getting over heated in warmer temperatures. Im on the lake and boat all summer so theyre perfect since theyre constantly getting wet. After a few weeks of ownership I can tell you that it was a success.
