Single Engine Private Pilot reported losing directional control and exiting the runway pavement during the takeoff roll. The pilot stated the type of shoes being worn were a contributing factor.

Narrative

Cleared to takeoff Runway XX for a west bound departure. Run my checklists. Everything looks great. Full power. Right Rudder. Just as I was approaching rotation speed (roughly 50-55 kts.) the plane veered sharply to the left; I knew I would not be able to recover. I pulled the power to abort the takeoff and continued off the Runway into the grass. I pitched up to take pressure off the nose wheel. I taxied over Taxiway 1 and into the next patch of grass until getting the plane slowed down enough to safely be on Taxiway 1. I called Tower and asked to taxi back to the FBO. I decided I would not be comfortable flying the plane so I left it there. I believe the issue may have been related to my footwear. I was in boots I wasn't used to flying in that have a 2 inch heel. After contemplating it; I think the heel of the boot added just enough height to give me leverage to make the breaks more accessible. I am to believe I let go of the right rudder too soon and my left boot was touching the left break. In the future I think it will be important to fly in flat tennis shoes.
