More brake boost?

[Supra2NR]

I was just crusing around and decided to try some heel/toe practice.I think I have the right stance for me ,but I wish the brakes were a little stiffer.Is there any way to increase the vaccume to the brake booster and get firmer brakes? I have giant feet so I can't truely heel/toe ,have to use the ball of my foot and roll onto the accelerator ,so too much pedal travel on the brakes is making an already akward move more akward.Also ,would anyone be know of any regular street shoes that are good for sensitve pedal controll? I realy don't want to buy special racing shoes

i know what u mean, im 6 ft tall, and i got size 12 shoes
in order for me to get good shift
i have to slide my foot to the clutch
and do the heel when releasing it
sumtimes i drive jus with my socks
to get better feel for the pedal
but, i agree with mrnickley, if increase the brake boost
its not good cuz the brake pedal wont have any feel anymore
so its harder to know how much pressure to put in the brakes

, but have u try the old converse all-stars?
i thought i was crazy too, but
they have thin soles
and they are flat and flexible
it actually helps me out when im driving
