I'll start off with my homemade smell/dampness aborbers.
Small kids' sized sock
Aquarium/Activated carbon (Pet store - comes in different size packages)
Dessicant / Silica Gel Crystals (Craft store - used for drying flowers or save the "DO NOT EAT" packets from shoes and purses)
Fill the sock about halfway with a 50/50 combination of the carbon and silica.
Tie a tight knot or sew the top closed.
Keep this in your skate bag to absorb any moisture and prevent odors from getting out of hand.
I've made these with larger socks and actually put them inside stinky skates like the Stinkeez, but far less cute. (I guess you could sew on buttons and make a sock-monkey out of it, lol)
I always leave my bag a little big unzipped to let air circulate, which also helps get rid of odor.
