Shoe length can vary depending on the design of the shoe, especially the toe box. To confirm your PIAR shoe size, it is best to measure your foot length rather than relying on your size in other shoes. Check out our Size Chart and Fit Guide for more details.

Have specific foot needs—like wide feet, bunions, or anything else?
We offer complimentary shoe stretching for a more custom fit. Include your preferences in the "Order Notes" box at checkout. If they aren’t perfect after stretching, you can still return them hassle-free.
