I have just been looking at the Walkaide. Im in the UK and here it is the OdStock FES device. The Walkaide looks better, I have the Odstock Device but it is such a pain to fit that I dont bother with it much. It was great to start with, my dead leg became 'light' but I got really bad burns from the pads on my leg.
It is all wires , one from the shoe and 2 from the electrodes which are cumbersome. The wireless Walkaide looks realy good.
