I still dont know if it is possible but If its not I would be fine with it. They don?t stretch either across the top. These are nearly 100% identical to the original pads, maybe a SLIGHTLY bit smaller shape, and slightly less round on the sides of the interior circle. The batteries have lasted longer than I need them every time. They come up a bit smaller than some flip flops. mids and highs were on point. The new 54? laces allow our child to double knot the laces which he prefers to do. Ich habe normalerweise 42 und die war hier von der Länge her optimal. To make sure I didnt just get a package with a missing code, I contacted the developers of the game, Survios. They got my feet perfectly, they do not stretch out and they were true to size for me.
