These are excellent. Fit any shoe including certain types sandals. Better than some I had made from the NHS. I am able to move them between different shoes. No need To but larger shoes fit to the 3/4 length.
Mt podiatrist suggested I try a pair of Powerstep insoles to help with Plantar pain. So far they are proving really effective. And being the 3/4 variety they are very easy to move from one pair of shoes to another. Full marks so far.
These were recommended by my NHS podiatrist as I have plantar fasciitis but have a really flexible hypermobile foot. It cradles my foot and stops excess twisting. This combined with New Balance walking shoes (again recommended) seems to be helping although if I use the insoles in other shoes that are more flexible I can feel the ridge in the middle but not much. A half sole allows your toes to move as well which is so much more comfortable. Fingers crossed this does the trick after 14 months of suffering!
