These boots will suit narrow to average width feet, but not extra wide. Choose the size that has an insole length 1-1.5cm longer than your actual foot length. Women with wider feet might choose men's sizing for a slightly wider fit - to get your equivalent men's size, go 1.5 sizes smaller e.g. Women's size 9.5 is equivalent to men's size 8.
See the Scrambler Trail Mid WP (Men) listing for men's sizing.
Xero does not provide width measurements, but we can advise so please reach out to us if you're unsure.
