I work in a deli, so a lot of meat and cheese gets stuck in the treads and it's really gross. This takes all the gunk out. It would be better with a long handle, though.
This is the best tool to clean your shoes, you can wear a glove to keep your hands clean.
Since I work indoors, the only things that get stuck to the tread of my shoes are mud (sometimes) and small bits of gravel (practically every day). These work perfectly for removing both, although I'm sure that, given enough mud, no one would have the patience to scrape off the entire shoe with one of these little things. For small things stuck in the tread, though, these are perfect.
This product is okay. It's sturdy and gets the job done, but by the end of the night my shoes are a mess. I just wish they were a little bit longer and had more teeth so that I can finish the job faster without getting as much gunk on my hands. If Shoes for Crews would provide that alternative I would gladly order a few! *WINK, WINK*
I love them I use them once a month to clean my shoes for crews and keep my shoes slip free
