Review on Wernies Arch Replacement Sports Shoe Inserts - Comfort And Extra Support For Running, Work Boots, Casual Shoes & Sneakers. by Marc Tufa

I bought these because I wore holes in the soles of my favorite shoes. My plan was to remove the old ones and put these in, but the old ones are really glued in there, so I just put these on top. There is a noticeable difference in the vertical space I have in the shoe, but the inserts are so comfy that it doesn't bother me. I'm a women's 8 and ordered the medium. Mine fit perfectly in my shoes so if you're any smaller than that, plan on having to trim them down a little.
