Converse to Merrell shoe size

The short answer

Converse 6.5 is Merrell 8.5 by the two brands' own charts.

At least one of the two brands publishes no foot length, so the rows line up the US size both charts print. Treat it as the label conversion, not a fit.

Every Converse Chuck Taylor size read across to Merrell. US men's sizes on the left, US women's on the right.

Tinted rows change label or sit between two sizes. 8 sizes have no counterpart on the Merrell chart. Read from the two charts only; no formula and no averaging.

What wearers say

Charts describe a garment. People who own both brands describe a fit, and their answer ranks above this table once five of them stand behind it. Pick your size in the converter to see whether there are enough yet.
