~25.5	25.5	7.5	41
~25.5–26	26.0	8	41.5
≥26	26.5	8.5	42

Target 26.0–26.5 cm internal. Standard "D" width, not 2E. Size up for toe room + heel-lock lace.

Fit principle

~1 cm gap between longest toe and shoe end. Created by choosing the right size, not by the shoe having a long nose.

Heel-lock lacing

Pins the narrow heel back so the foot can't slide forward. Watch how →
