What is heel-to-toe drop in running shoes?

Heel-to-toe drop is the height difference between the heel and forefoot of the shoe (stack height differential). 0mm = zero drop; 4-8mm = minimal; 8-12mm = traditional. Higher drop is associated with heel striking and increased knee extension moment.

Should I transition to zero-drop shoes?

Transition should be gradual (months). Sudden switch to zero drop increases Achilles tendon and calf loading by 20-30%. No single drop is best for all runners; injury history, anatomy, and running economy all factor in.
