Can anyone recommend a light, breathable and high arch support shoe? I am wearing my running shoes as I cannot find anything comfortable for my feet?
Don't wear running shoes. I'd recommend the Nike Vapor 9 (use Superfeet to fit your arch better) or the Air Max Cages. Both have a breathable, light, running shoe feel but with the lateral support necessary for tennis. Asics Gel Resolution 5 are another good option.
