Converse to lululemon shoe size

The short answer

Converse 5.5 is lululemon 8 by the two brands' own charts.

Both brands publish the foot length each size is built for, so every row matches a foot, not a label.

Every Converse Chuck Taylor size read across to lululemon. 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 lululemon 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.
