Do heavy boots impact your driving with manual transmissions.

19. Ihave an uncle who can speed shift a John Deere

Tobin can drive for hours without using the clutch, with a 13 speed Roadranger.
He could drive my full provenance ProShifted, A833 Drag racing transmission from here to LA without grinding a gear, at road speed. Don Carlton could carry the front wheels through 3 shifts in the same style trans, In the famed Motown Missle.

I tried one on a test day at Loudon (road course), under ideal shoes, pedals, and an exquisite clutch, with a stout W2 340. Maybe God could shift it,or Bill Rutan. If I missed a demi step in "footbox ballet", the mayhem was more than I wanted to manage on Mt. Washington! I sweated liquid sodium until Liberty Gear MADE a new, OE style, synchromesh input shaft,from an old ProShift one. I got it in my hand in time to put it in the transmission, help my "crew" swing it in, and load the car. I may have grabbed a shower before the train rolled out. Liberty ate the airfreight bill, because awesome.
No single answer exists. Uncle Tiny and I take a size 14 boot, Tobin ain't a midget. Before I had racing shoes, a Herman "Soft Sole" workboot worked best, 'cuz you didn't have to ducttape the laces. Chuck Taylors dissolve from all the things that happen in a race car.
