Sidi Dominator MTB Shoes
I've owned three pairs of Sidi's over the course of my cycling career. My first pair, a pair of road cycling shoes, I purchased in 1996 and had to be retired in 2000 because I had to walk 8 miles back to my apartment when I double flatted in the foothills of the Rockies. This absolutely trashed the soles. The pair I purchased to replace them are still going strong almost a decade later (I've also since learned to carry a patch kit along with a spare tube).
My Sidi Dominators I got right before this 'cross season. They are awesome! Granted I was coming off an old pair of Shimano MTB shoes circa 1994 so you have to consider the basis for comparison...
Smart Wool Socks
These are great for keeping the tootsies warm during those late season cyclocross races. They are soft and cozy, I even wear them off the bike. And they are machine washable. Bonus.
Dumonde Tech Chain Lube
I've tried the gamut of bike lubes and this one is my all-time favorite. It's really long-lasting and it holds up remarkably well in all kinds of conditions. The only thing is, you have to wipe your chain an awful lot after application.
