Booties are hard to get dry and even after an entire day in the sun they can still feel damp inside. After a good day of diving I soak them for a few hours in detergent, rinse them with the hose and then pour in a good dose of Dettol or Savlon, swirl this around and then hang them out to dry. Because of the unknown origins of the feet that are put in rental booties I try and keep the inside healthy!
I find it best to leave them on a rack in the shade and in a draft and eventually they do dry. Once dry, I silicone the zips and work them up and down a few times to spread the silicone and dust them liberally with baby powder. They are now ready to be stored or used again.
Many of the same principles that I apply to smelly wetsuits in this post also apply to booties.
