These high-heel add-ons are ok. I wore them for my 20 minute wedding ceremony on the grass at a golf course. They helped me stand tall without sinking, but got stuck in the grass several times and came off inside before I even made it outside. I also bought enough for all of my bridesmaids to use, but only those who had the smallest heels on their shoes (like stilettos). Even slightly wider heels on the back of the shoes wouldn't let these protectors stay on. None of us are going to use them again or would recommend these to other people.
