What is Zero Drop?

Zero Drop means there is no height difference between the heel and the toe of the shoe. Your foot sits flat, just as it would if you were standing barefoot on the floor.

Note: A shoe can be "Zero Drop" but still have lots of cushioning (e.g., Altra shoes).

The Benefits

1. Natural Alignment: Aligns the spine and posture more naturally than heeled shoes.
2. Achilles Loading: Encourages the Achilles tendon to lengthen and load like a spring.
3. Better Form: Discourages heavy heel striking (since there's no chunky heel to land on).

The Risks

If you are used to a standard 10mm drop shoe, your calf muscles and Achilles tendons are functionally shortened. Switching to Zero Drop forces them to stretch further with every step.

• Danger: Sudden transition = Achilles Tendonitis or Calf Strain.
• Solution: Rotate them in slowly. Start with walking, then short runs.

Is Low Drop the Same?

No.

• Low Drop: 4mm (Common in Hoka, Saucony Kinvara).
• Zero Drop: 0mm (Altra, Topo Athletic, Vibram).

Zero Drop isn't a magic bullet, but it is a tool that forces your lower legs to wake up and work.
