What is drop in footwear and why is it 0 mm in barefoot shoes?

Drop explained in 60 seconds (with simple examples)

The drop is the difference in height between the back of the shoe (heel) and the front (metatarsals). If the back is 20 mm and the front is 10 mm, the difference of 10 mm would be the drop. Let's say it's a kind of "heel" that is intrinsic to the sole of the shoe.

When we talk about barefoot shoes, the goal is for all their characteristics to be like walking barefoot, so walking completely flat is much more natural than walking with some inclination.

That's why barefoot shoes have a 0mm DROP, because the height of their sole is the same at the heel as it is at the metatarsals.

If the heel measures 5 mm and the metatarsals measure 5 mm, the difference in height is 0 mm, so we have a 0 mm DROP, or as it is commonly said, "no drop."

How to measure the drop of your sneakers at home (marble method)

Very easy. All you need isa marbleand aflat surface:

1. Leave the shoe on the surface.
2. Place the marble in the heel area, on top of the insole.
3. Observe whether the marble moves forward (this would indicate that there is no incline and therefore a positive drop), and if the marble remains stationary in the heel area, this means that there is no incline, and therefore we have a drop of 0 mm.
