I've found that leaving a tea bag in the shoe in between sessions can help to lessen (but not erase) the smell. My climbing shoes used to smell like cheesy Doritos, but now they smell more like a very weird cup of tea.
I'm surprised no-one's mentioned Bicarbonate of Soda yet - I've always sprinkled a thin layer on the inside of my shoes, given them a shake, and left them for a few days, once every few months, and it's always worked surprisingly well.
The downside is getting it all back out so as to avoid having bits digging into your feet when you use the shoes again - I always use a vacuum cleaner with a thin nozzle.
I do have evolv vtr's and just washed them along with my kit bag. The majority of the rancid stench has gone however there is a still a faint smell when you get up close and personal. I'm taking them to church in the morning for a exorcism I'll keep you posted
3 months? You must be doing something wrong! Lol mine last 3 years haha they did start smelling after 2 (-ish) years, I don't like wearing socks...
Regarding smell, I washed mine and used athlete's foot powder. Most of the smell has gone but having the powder in is a bit annoying because you can't get rid all of it so for a few sessions you might feel that your foot is slipping inside the shoe a little - was fine after a few sessions...
1) What are boot bananas like for drying out boots, do the work like absorba balls?
2) Do banana boots smell of lavender as my bf hates that smell (was thinking bday prezzie)
3) My shoes live out of the bag, the smell if you sniff them, but one of my old pairs of climbing shoes (Montrail) live in a plastic sealed bag.
