I bought a pair of sneakers and found after wearing them that they were a bit narrow. I looked at a lot of shoe stretchers and decided to get these as A)They came as a set instead of just one.(Honestly, ONE stretcher?! How ridiculous is THAT!?) and B)They were made of wood, which is sturdier than plastic.
I put the little bumps in, put them in the shoes and cranked them tight. After leaving them in 2 days, the shoes were so much more comfortable. Good product, well made and do what they say they will....can't beat that.
