I work for a company that produces ozone generators and in my spare time I am working on developing a product that will remove the smell from our rock climbing shoes by pumping ozone into a box, the ozone then attaches itself to all of the smelly odors which are then exhausted out of the box leaving your shoes odor free. The only problem is that thus far its looking like it will resale for about 60$. I am wondering if anyone here would be willing to pay that kind of money for such a contraption. The longer the shoes are left in the box the less they smell but I am having results after about an hour. This is a much safer alternative that throwing them in the wash machine and its all done without water so there will be no harm to the leather or rubber. Any feedback would be much appreciated. Thanks

I would probably be disincline to buy one for myself as it's a really specialized thing. But I think it's something that resolers might be interested in having.

Thanks I have a hard time believing that this is true. Ozone is extremely toxic and reactive and a powerful oxidant. How could this could possibly be safer and not react with leather or rubber? I have no doubt it kills bacteria!

Thanks $60 will buy me a decent quantity of Desenex anti-microbial/fungal foot powder. Between that and letting my shoes dry out thoroughly outside of my pack, I've never had a problem with funky shoe smell.

Ozone is VERY safe. Some of the applications that we build our products for are: hospital air purification, many of the top bottle water manufacturers treat their water with ozone, cleaning water for wine making, home air purifiers, etc.... "Ozone Therapy is Safest Known Therapy Ozone has been found to be an extremely safe medical therapy, free from side effects. In a 1980 study done by the German Medical Society for Ozone Therapy, 644 therapists were polled regarding their 384,775 patients, comprising a total of 5,579,238 ozone treatments administered. There were only 40 cases of side effects noted out of this number which represents the incredibly low rate of .000007%, and only four fatalities. Ozone has thus proven to be the safest medical therapy ever devised. " source http://curezone.com/...sp?a=92,634&q=76 edit: obviously we do not concentrate the ozone to a level where it can be toxic

" source http://curezone.com/...sp?a=92,634&q=76 Not claiming to be an expert, but the US-EPA says different (taken directly from the US-EPA website): "Breathing air containing ozone can reduce lung function and increase respiratory symptoms, thereby aggravating asthma or other respiratory conditions. Ozone exposure also has been associated with increased susceptibility to respiratory infections, medication use by asthmatics, doctor visits, and emergency department visits and hospital admissions for individuals with respiratory disease. Ozone exposure may contribute to premature death, especially in people with heart and lung disease." http://www.epa.gov/...ollution/health.html The poison is in the dose. Even water is toxic in enough quantity. What concentrations does your device produce, and what is the chance that any of the ozone produced ends up outside the device and in the air that we breath? How do you know that the concentrations produced have not affect on shoe rubber or leather? Basically sounds like an elaborate, expensive solution to a not-so-big problem to me. Your link also looks pretty much like propaganda to me. Even if ozone is a valid medical therapy, which it might be, we are not talking about a treatment whose benefit outweighs the risks...we're talking about making shoes smell better.

I showed that article to one of the sales people and he replied with "The amount of ozone produced by this unit is so miniscule that its completely safe to have one sitting in your living room with you all day everyday." I just do the engineering here so I am no expert on the effects and whatnot, I just know they sell a ton of them as air purifiers so I repurposed it as a shoe odor remover because all I can think about at work is rock climbing and this was one way to combine them. Its kind of a big problem for me, I live in a small apartment so they can easily smell up my apartment in no time flat. I also think its kind of expensive that's why I'm putting out some feelers here before I just make one for me and leave the idea at the wayside

The gym I used to work for tried out an ozone air purifier for reducing shoe odor. It did not make any discernible improvements to funk in the vicinity of the shoe racks, let alone in the shoes themselves. This was even running at full tilt. Regarding toxicity or other negative effects, the ozone's own odor was very noticeable and employees did complain about mild nasal irritation. We retired the unit after one season of use due to lack of effectiveness and high energy costs. I hate to come down as really negative here, but the general consensus (both peer-reviewed and anecdotal) is that ozone air purifiers are both ineffective for most general applications and potentially harmful.

I would like to think that my company builds a superior ozone unit, but only the testing that I am currently doing will tell. I'd be curious to see how it would work, if at all, in a concentrated application. Ozone has very little effectiveness in anti-bacterial/fungal/viral/microbial applications, except at levels that are deemed unhealthy. Furthermore, high concentrations can deteriorate rubber and plastics. From a functional and health standpoint, UV and good ventilation would probably be more effective for getting rid of odor producing bacteria, but who knows what it will do to the shoe rubber, leather, synthetics, etc. I'm sure there are plenty of Brookstone/Sharper Image type gadgets that are marketed for this purpose that make equally dubious claims as the ozone air 'purifier' crowd. I say just wash 'em once in a while.

A 'Society for Ozone Therapy' is hardly an objective source for an unbiased study. Combined with the actual physical harm ozone can cause and overall ineffectiveness for air purification (hell, ozone itself is an air pollutant), I'd call your company's product and others like it an outright scam. I apologize for any offense if your original post was earnest, but any ozone-emitting device that claims to clean air is a bunch of nonsense/bollocks.

Ozone in ambient air exhibits adverse physiological effects in humans at levels as low as 0.0000008 percent. It damages rubber at these levels but I suspect long-term exposure is needed. Several years ago, air purifiers became quite popular. A well-known Consumer group examined these and IIRC concluded that the "ion generator" types were mostly ineffective but offered some benefit in principle. The "ozone generator" type was deemed unsafe. I am reminded of a quote - unfortunately I'm not very good with quotes so I can't repeat it verbatim - that says it's hard for someone to see the facts in a situation when their livelihood depends on them disregarding those facts. This was offered in connection with G.W. Bush and his tie$ to Big Oil and their interpretation of global temperature data, but maybe it fits the OP here as well.

Thanks No, I wouldn't buy one. Assuming it works, which is yet to be proven, it would not make sense for an individual climber. But maybe large-scale facilities such as gyms, resolers, guiding outfits, etc., might be interested. I have a much cheaper solution that so far appears to be working amazingly well and doesn't require you to lug an ozone-generating box with you on trips: drypointe shoe inserts. http://www.etsy.com/shop/DryPointe I have been thinking of getting these shoe inserts for a while, but never got around to it, until this spring, when I got a new pair of shoes and had an opportunity to get a pair of these inserts the same weekend. I think they would not work too well on the shoes that are ALREADY smelly, but I got a pair of those balls when I got a new pair of shoes, and after a few weeks of climbing there is no smell to the shoes at all (normally by this time they would be getting noticeably ripe)

I use DryPointe shoe inserts too. They dry up the sweat, they are inexpensive and my shoes that usually stink don't. No nasty chemicals to hurt your shoes or your feet. Also, the company is climber-owned and she donates money to the Red River Gorge Climbers Coalition and Friends of Muir Valley with every set of DryPointes sold.

Thanks As a polymer chemist, one of the tests I've regularly done over the years is ozone resistance of plastics and rubbers. Ozone is a free radical and is very detrimental to polymers. I suspect that using this device regularly would lead to quick embrittlement of the shoe rubber.

My familiy is pretty religous about powering up the inside of our shoes after every climb with any Dr Scholes type powder and none of the shoes have any smell. The back closet has 10 pairs of climbing shoes but you can't smell a thing.
