Know the term
Heel-to-toe drop describes the difference in sole height between heel and forefoot under a stated measurement method. It is separate from total stack height.
Compare the method
A manufacturer’s nominal figure and an independent measurement may use different methods. State the source and avoid presenting a difference as proof that either party acted dishonestly.
Keep personal context
Do not infer that a particular drop will prevent injury or correct a running style. A large change from familiar footwear deserves a cautious, individual approach.
Record a useful review
Include your previous shoes and what you actually experienced. Distinguish comfort observations from medical conclusions.
