Crep ProtectRefresher Pill - Ultimate Shoe Deodorant, Fresh Cotton Fragrance - Black

They work. They help dry my gym shoes out after sweaty workouts and more importantly my gym shoes do not smell. You can adjust them depending on how damp your shoes are.Highly recommended

Trainers got soaked and started to smell damp, this product helped them to dry out quicker giving them a nice scent.

Good product - but the smell I was trying to get rid off didn’t disappear... after 5 days of trainers being in a box with the product in them, I could smell the crap pill smell but also the original odour to.Does a job but not as strong as I think it needs to be.

Expensive and not as effective if the shoes are used often

As other reviews have highlighted, they don't really remove odours or even mask them. Smell is pleasant but very mild, too mild to have any effect. Left them in my boots for over a week and still smelt bad.

I have tried all kinds of products to combat the smell of my sweaty trainers and nothing comes close to this product. It’s simple cheap and so so effective. Love the two pronged attack of absorbing the moisture and at the same time leaving behind a subtle fragrance. They have prolonged the life of my trainers threefold

Had tried cleaning, shoe fresheners and sprays etc and they just masked the smell. These work very well. Greatly improved nasty smells from old trainers so they are were able and don’t make the room or cupboard smell; now using on new trainers, they are brilliant at keeping fresh despite my son wearing no socks! Having read other reviews I think people are expecting too much!

A week without changing shoes and the smell hasn't changed... At least it has a different shape now...Anyway, I'll stick with Peusek powder or Fungusol, they work better...
