To ensure longevity of any new kicks you have just purchased in anticipation of the new season, I can strongly recommend this:
Designed for boxing gloves but also conveniently fit inside basketball trainers. They are basically pouches of activated charcoal which absorb any moisture left trapped inside after a hard session on the court. Basically no moisture= no bacteria= no smell! Shazam! Long lasting trainers and a kit bag that doesn’t smell like decomposing trout! If they start to lose their effect a couple of hours in direct sunlight and they’ll be good as new: simple science, basketball magic!
