MTB shoes purchased in 1999. Used for daily commuting since 2007. In pretty decent shape but had three consecutive wet rides a couple weeks ago and now they kinda stink. How should I clean these? I've never washed shoes before so pardon if this is dumb question. Should I just soak in a bucket of water and detergent for a couple days? What about bleach? What about just putting them in the washer and dryer. Any ideas are appreciated!
