At risk of stating the obvious:
It's hard to impossible to do much of this fancy footwork on the brakes and rudder if you don't have good feeling and agility through your shoes.
I started in a '41 T-Craft with worn-out heel brakes. Then I transitioned to a 170B with well-adjusted, responsive hydraulic toe-brakes. Problem was, I had come from Alaska to Maine to ferry this airplane home, and I had brought some stiff, heavy leather boots as my camping out, survive-in-the-wilds of Canada, all-in-one footwear. The first evening of T&G practice ended with us hitching the tail spring to my friend's pickup truck, pulling it back onto the runway. (fortunately, only got off into grass and mud, and no harm done,)
Next day, a trip to the shoe store for some light running shoes with total ankle mobility, and I was back in the saddle without further problems.
Now that I have more time in the 170, I don't sweat it nearly as much, but for learning it was huge.
I also would like to make a plug for Steeger Mukluks in winter: http://www.mukluks.com/ Most winter footwear is extremely rigid, clunky, and not always easy to wriggle your toes to warm them up. I have a couple ski flying seasons now in Steegers, and I'm completely sold. Also, they don't have any eyelets to scratch up the cowling when you're climbing up to fuel a high-wing.
Happy landings,
-DP



Oh, I just couldnt resist. This thread actually has some great information that I'll ponder if I ever need it.
