How to Find Your Size

Stand on a piece of paper in socks, trace your foot, and measure the longest point from heel to toe in inches or centimeters. Match that measurement to the charts above.

Fit Notes by Brand

Most of our shoes run true to size. If you fall between two sizes, go up half a size for a more comfortable fit. A few brands have specific tendencies worth knowing.

Johnny Famous — They are generally true to size, if you are unsure about your size it is always better to size up rather than down

Spring Footwear (L'Artiste, Flexus, Azura, Patrizia) — runs slightly narrow. Size up if you have wide feet or prefer a roomier fit.

British Walkers — fits medium to slightly wide. True to size for most; if you have narrow feet, consider going down half a size.

Birkenstock — uses EU sizing as the primary size. Refer to the EU column above. Regular footbed fits most; narrow footbed available on select styles.

Clarks Originals — generally true to size. Desert Boots may feel snug at first and break in within a few wears.

Nike, Jordan, Puma — true to size for nearly everyone.

Adidas (including Yeezy) — tends to run slightly large. Consider going down half a size if you're between sizes.

Why Don't Panic Shoes

Family-owned on Jamaica Avenue in Queens, New York since 1987. Three generations of New Yorkers have trusted us to help them find things that actually last.

Every brand and every product we carry is hand-selected. We do not stock shelves with whatever the distributor is pushing this season and we do not chase trends for the sake of it. We bring in brands and products we genuinely believe in — the kind that hold up, look right, and mean something to the person who owns them. Whether you are buying shoes, a belt, a watch, a jacket, or anything else in our store, it earned its place here because we would buy it ourselves.

When you have a question a real person picks up. Usually Dave or Joe. No bots, no ticket system, no automated runaround. Just the kind of honest straightforward service that used to be standard everywhere and is genuinely hard to find now.

We have been on Jamaica Avenue since 1987 because we take care of the people who shop with us. That is the whole model and it has never changed.
