I'm a big boy. 6'3" and around 320 lbs. Part of the problem with me being a fat boy is that I developed tendinitis in my feet at the early age of 30. Now I'm rocking the walking boot again until I can get to my doctor who will give me Prednisone and I won't flare up again until late summer.
As such, it's impossible to drive my car with the boot, and with a regular shoe it causes enough pain that I worry about the integrity of the gearbox components.
Today is one day I wish I had an automatic.
