ASICS Shoe Size Guide & Sizing Chart

Direct Answer Summary

ASICS performance running shoes fit true to length with a tailored athletic lockdown, converting a US Men's 10 to EU 44 and 28.0 cm. Because long-distance running causes foot swelling, ASICS recommends sizing up a half size or choosing their dedicated 2E (Wide) or 4E (Extra Wide) models.
