Review on 👟 Sof Sole Replacement Steel Track Spikes: Enhance Your Running Shoes with Pyramid Design by Stanley Molden

This is a poor quality product. Look elsewhere and save your money. There is virtually no play on the spikes, making screwing them in with the included wrench impossible. I had to screw them in mostly by hand as the wrench is useless and the spikes are not shaped properly. I lost two spikes the first time. I will look for another source.
