Ellis HarperShoe Ninja Shoe Deodorizer - Shoe Odour Eliminator with Activated Charcoal, Versatile and Reusable Deodoriser Bags for Shoes, Football Boot Deodoriser and Shoe Smell Remover, Great for Sports - 2 PackClimatePartner certified

These work great and have lasted me ages. Definitely helps with the smell in my shoes and fits well into all my shoes.

2nd Update after 2 months:Brilliant. After two months of continuous use I can confirm that my football boots have been cured of all odours and don't smell at all. On that basis I would recommend them.UPDATE:Originally I said these didn't seem to do much for smells but I left them in my football boots for a week after that and when I went to put them on I noticed the smell had completely gone. I wore them the same day and when I got home I noticed there was a slight smell and they were quite wet so I put the Ninjas back in and the next day they were completely dry and no smell! I've updated my review to 4 stars as a result.Initial Review:I bought these to put in my football boots which had started to become a little bit smelly. I wouldn't say they were bad, they just smelt a bit if you stuck your nose in them. Anyway, I put these in on a Sunday and took them out on Wednesday and they smelt just the same, so there you go.In terms of drying out shoes, my boots were a bit wet from hot feet after my game so I put the Shoe Ninjas back in the shoes when I got home and they do seem to have dried out pretty quickly, but I can't say they wouldn't have done that anyway now that we have the heating on.I like the environmentally friendly nature of them, and I'd much prefer to use something like this compared to sprays and chemicals etc and perhaps if you have brand new shoes and use them from the outset they might eliminate odours but for pre-existing problems they don't seem to do very much.

Quick delivery, good price and seems to work well

I purchased these to help prevent smelly shoes, as I have to wear the same shoes every day for work. I have tried spray products before but I always find they are good to begin with and then after you put them on, it does nothing, just like a fancy deodorant with no antiperspirant properties.These shoe ninjas partially do what they say - they neutralise the odour, but only around the shoes, not in the shoe. It doesn't help by removing the smell, but it does help with the moisture build up in shoes that usually causes smell. It removes a good amount of moisture, but for me it just doesn't really help with the smell, which is unfortunate.

I was sceptical about it, but thought I would give it a go.....My work trainers were getting a bit sweaty so I decided to give these a go.I placed them inside my trainers at 3pm until 7.30am on the first night and there wasn't any change, straight away thought it was all a gimmick. But carried on using them for a few days, and slowly but surely the sweaty trainer smell has all but disappeared.I would recommend these, but it won't work overnight. Give it at least a week for them to work. I found it best to slide them all the way in to the shoes for them to start working.Great product

Doesn’t work, awful and my shoes aren’t even that stinky.

Bought for my grandson to put in his football boots after training to keep insides dry and deodoriser appears to be working, would recommend these

They seem to work very well.I plan to get more of them for my husbands trainers next!
