I mean really offensive. What can I do? Washing machine? (They are Hoka Biondi’s)
I put mine in the washing machine (warm wash with detergent and 1/4 cup of Clorox). Add the bleach once the washer is full of water to prevent fading.
Air dry.
Quit pissing in your shoes! 
Shoe trees. Cedar shoe trees. Double the life of your running shoes (and dress shoes, too). I have about 10 pair. They stretch your shoes out like new, get rid of the stink, and make life new again. You’ll thank me…
I have never had shoes stink UNTIL I started wearing Hokas. I think they act like sponges and absorb sweat BIG TIME.
I hand wash them in white vinegar and baking soda.
I may try the freezer trick.
Put some vinegar on the insole. It kills the bacteria.
Maybe consider Kiehl’s Dry Run foot cream, in addition to whatever treatment you end up giving to the shoes themselves? My feet, and shoes, have always been weapons-grade, but since I’ve started using this they’re much less offensive. As ever, YMMV.
Stop sniffing your shoes.
My shoes smell like 100 cats pissed on them. Mrs. Printer will not even let them in the house. Therefore, the washing machine and the freezer are off limits. When I travel with my running shoes, they are wrapped several times in plastic. Is there some kind of spray?
Boot dryer.
This morning, with my shoes banished to the basement, I get in my car and the shoe smell lingers. Its bad!
Replace them.
I have the same problem, and can’t seem to get rid of the smell. My husband says they smell like toxic corn flakes!
Tried the freezer, tried Knock-Out (spray), washing machine…they seem to kill the smell a bit, but as soon as I run again, it’s back. I have a pair of shoes under my desk right now, and I feel sorry for my desk neighbours, but I don’t know what to do otherwise. It doesn’t matter what brand I’m wearing either…
If anyone has a sure-fire way to kill the corn flake smell please share!
Tried the vinegar this morning. Only problem, they already smelled like vinegar before I drowned them in white vinegar.
I can replace the shoes, it’s my custom insoles that I cherish, but also are what smell.
I’m going to try peaches and onions like from the movie Holes.
bucket of water, white vinegar & bleach (obviously diluted)…soak for long long time…let air dry.
No idea how it worked or what other special juju he put on them…but my horrid bike and run shoes that had been forgotten for a couple days while soaking wet (& sealed) in the dark recesses of a race bag & then trained in mercilessly for a couple months have been resurrected by the boyfriend. The bike shoes are blindingly white, too. These things almost rode on top of the car on the way home from Chattanooga…funk was lingering in the car for days. Really they were just gross.
I haven’t mustered up the courage yet to tell him that the run shoes were probably done anyway…but they’re pretty again.
And I do think hokas are nothing but a giant sponge…they squish after they get wet…
I have actually had luck with a UV light shoe thingy. Takes forever for it to work on an old pair but new pairs are staying better. A gift from the mother in law so you know it was serious.
At Challenge New Albany - one of the vendors had a spray he said he used on his shoes for months and infact had a running top he had used several times - and sprayed on his product. I took a couple of samples and now have ordered three bottles of his stuff- Gotta Dash Sport is the company and the product is All over Body and Gear. This stuff is amazing - even used in on my dawgs after they went into stinky ditch water.
So very week or so I spray my bike and running shoes and no smell at all.
Usually caveat- I have no commercial interest etc. just a great product.
Hope this helps
For years I have been washing my running/cycling shoes fairly frequently in cold water (every 3-4 uses for running shoes maybe 10 uses for cycling shoes). I live in Orlando and during the summer months, sometimes more frequently. For the runs that I don’t wash them, I make sure I remove the insole and allow them to dry out. I usually have a rotation of 4 shoes going so I don’t need the same pair more frequently than every 5 days and that gives them a decent amount of time to dry. If I stick my nose directly into them and sniff, they probably don’t smell great, but they are not offensive from a distance of more than a few inches.
Put them in the freezer overnight then try soaking them in a bucket of oxyclean for an hour. Toss them in the dryer with a couple of towels for a few minutes then let them air dry. Should be good as new.
go to hunting section of sporting goods store and buy a smell remover spray.
Upwind is the brand I use because it’s made here in Cincinnati area and I have a friend who works there.
Use a liberal amount and it will get rid of the smell.
Hunters are crazy about smell and the stuff works.
