GAIT Happens Foot Health Care Kit I was recommended this kit when I hurt my knee, and I purchased it along with shoes at Stride Lab. I tried the toe spacers (size M) and the ball a couple of times. Due to my tendency to give up easily, I haven't used them since. I'm offering this for sale in the hopes that someone who is more dedicated to foot care and foot training will use it. I've included a link to the official website below: https://shop.stridelab.jp/products/gaithappensfoothealthkits25ss The kit contains everything. The spacers and ball have been disinfected with alcohol.
