Ellis HarperShoe Deodorizer, Bamboo Charcoal Shoe Odour Eliminator Bags, Foot Deodorant Inserts - 2 Pack of Shoe Fresheners with Nail ClippersClimatePartner certified

Can confirm it both prevents smell and eliminates smell, and there's no fragrance!I got these for my work boots and they still smell brand new. I leave a 2nd pair of socks in my boots and putting the shoe ninjas in the socks, in the boots, got rid of the awful smell.Just bought a second pair to put in my everyday trainers.

I add a few drops of essential oils to these to make the trainers smell nicer.

Product looks good. However missing clippers causing 4 stars

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

This product has prevented my rooms from being haunted by the stench of a long day's work, that's for sure but as far as what was advertised to me, it falls short.Even with regular foot hygiene, I don't know if my shoes and insoles are too far gone for this product fails to re-deodorise the shoes and prevent smells.I regularly recharge my charcoal pouches in the sun during the day when I'm out, and I'm sure this allows them to keep preventing the smells from escaping from the shoe once inserted, however, I am disappointed that it doesn't give protection for the next day and reverses the issues I've begun to have.If you're looking for a fix, this product isn't it, but if you're looking for something to help your co-inhabitors stop complaining about your smelly shoes, it does the job.

Completely useless.Have been in my boots for weeks and made zero difference. Certainly not worth the money.

These really work! I needed a solution for leather rugby boots that smell horrendous usually. When the boots aren’t being worn, the shoe ninjas pretty much live in them and no more odour issues. I even bought a 2nd pair so that there’s a set for both boot types.

Does a good job
