The special devices fabricated for our sock designer, Dion Shaw from 4Shaw. Dion likes his colours so we were happy to oblige.
When you order a pair of custom Cobra9 Pros, you can design many of the features of your footbeds in conjunction with your specialist. Colours can be hand picked, but you can also help decide the weight, stiffness and level of cushioning you want as well.
