Input:
I ordered these because I have mostly hard wood floors on my main floor and occasionally like to scrub them by hand. These are an excellent product to keep my knees from getting sore. They are very tight-fitting, though, and there is no way to adjust them to get wider. So, if you have skinny legs, this product is for you!
