How fast can my humanoid run?

The fluff:

I have a humanoid who's about to breach a door. He's got some upgrades to his body and can pump some stimulants through it to boost his strength, resiliance and speed to ridiculous proportions for a short while. When he breaches the door he's going to accelerate from a standstill and run into the room as fast as he can.

The problem:

Many questions have asked about the maximum speed a humanoid can run, but not covered the angle I'm thinking off. When ignoring things like muscle limitations, bone and flesh resiliances etc. You still are limited in your maximum speed. This because if you push off you will eventually start slipping, the surface you are standing on will eventually crumble under the stress you put on it, after every push it takes a moment before gravity pulls you down and your feet touch the ground and air resistance will limit your maximum speed.

The data:

My guy with all his clothing weighs 110 kilo's. He is standing with shoe-rubber on dry, rough concrete. His feet are 23.8cm long and he's 180cm tall.

The constraints:

My guy has a body that can handle anything you throw at it in terms of strength, speed and resiliance. Its his environment that limits him.

The question:

My guy is about to run full-speed from a standstill. His body can handle it, but the environment has its limitations. How fast could my guy achieve maximum speed without destroying his shoes or the concrete he's standing on? What would this maximum speed be?
