The best piece of gear I own was purchased for me as a Christmas present this year - I have to admit I was under-whelmed when I opened it and was skeptical that it would work... HOWEVER...
Stop what you are doing, and go get a PEET Boot Dryer TODAY!!!!
This thing has saved my running shoes from smelling like a swamp and gets them dry and runnable overnight every time - even if I soak them in the shop sink first.
Its really a simple machine. The model I have is just 4 tubes with shoe forms on the top. These forms have holes in them and when you plug the contraption in it allows gently heated air to convect up through the shoes... You almost can't tell the thing is on - It doesn't blow air like a hair dryer.
In the past I have tried stuffing my shoes with newspaper (you have to keep changing the paper) or putting them in front of the register (so everyone in the house can enjoy my shoe stank)... Invariably, the shoes would stay damp too long and usually developed some hideous bio-hazard smell that made me want to transport my shoes on the roof rack instead of in the car... Now I don't hesitate to run my running shoes through a wash cycle in the washing machine and rack them up on the PEET to dry - BRILLIANT!
Would be fun to hear about any other gear favorites there might be out there... Comment away and share the wealth!
