They match perfectly with our metal chair legs from Restoration Hardware. For some reason the original plastic bottoms broke off after 4 years of using the chairs. My husband tried using these white silicone protective condoms on his lower legs but they looked horrible, they kept coming off, couldn't easily move chairs across the floor and the chair legs ended up cutting through them. I then put more effort into finding these plastic ones, measured the inside of the cane leg and ordered them and they fit perfectly! I had to use a soft mallet to hammer them in, but they fit perfectly. Now the floor is protected, they look nice and my kids can slide their chairs in and out with ease.
