hi everyone. Has anyone got this good splint (its a lot better and stronger than the Foot up). I have got one of these, and now the weather is warmer I don’t want to have shoes on all the time., so I want to get thes hoeless adapter, I know there is one, it is pictured on the box. I can’ t find one,on the website, it shows the part number, but no option to buy it. Does anyone know how to get one?
