Heel2Toe is a therapeutic wearable that attaches to the side of your shoe and delivers positive auditory feedback each time you make a good step. Heel2Toe automates a physiotherapy gait training strategy: place your heel first when walking. This simple strategy lengthens your stride and changes a stooped, shuffling gait pattern to one that is upright and striding. Walk-BEST (BEtter, Faster, Longer, STronger) with Heel2toe, led by physiotherapy professionals and professors from McGill University in Canada, and University of Exeter in the UK.
