Most customers find this series runs very small.
Most customers who wear a half size, order 1.5 sizes up. Most customers who wear a whole size, order the next size up.
For example, a size 8.5 should typically order size 10. Size 9 should typically order size 10 or even 11. Boots that are too tight lead to cold feet. Be sure to leave room for optimal air flow!
Special note! Some customers who wear the Baffin -148°F boots and are not highly active prefer to err on the side of the boots being too big rather than too small. Some customers do order 2 sizes up, knowing the boots may feel a bit large but choosing to opt for more air flow. One size up works for most, but if don't have time for an exchange, you may wish to select 2 sizes up to start. You can always add more socks, but you can't create more space if the boots are too small for you. Questions? Contact Us!
