I'm trying to remember the brand name of some racing flats we used in high school in Kentucky in 1973. They were white with 3 blue stripes on the sides, flat hard soles maybe 1/2 inch thick at the most in the heel area and less on the forefront. Very thin uppers. We used them for everything from cross country to track mid to long distance. Training and racing both. This was in the pre Nike era. Any of you oldsters out there remember? Someone told me they are still in production.
