Running Sneaker Store Near Me on Fifth Avenue: New Balance Flatiron

New Balance Flatiron Flagship will scan your feet in 3D before you try a single pair. The store is at 150 5th Avenue, at the corner of West 20th Street, and it opens at 10:00 AM Monday through Saturday and 11:00 AM on Sunday. For anyone searching sneaker store near me between Union Square and Madison Square Park, this is the place to go when fit matters more than hype, especially for running shoes.

The storefront sits in the base of the Methodist Book Concern building, a Romanesque Revival block designed by Edward H. Kendall and built between 1888 and 1890. The publisher printed religious books and periodicals here before moving to Nashville in 1939. The top three floors, with their medieval-style battlements, were added in 1909, and a 2001 reconstruction restored the original ground-floor design that frames the shop windows today.

New Balance has run its Flatiron flagship from this corner for more than a decade. In September 2025 the company reopened it after a remodel modeled on its Boston flagship, with wood fixtures, exposed brick and a facade opened up to let in more daylight. The brand describes itself as independent since 1906, and the store page calls this location a destination for running and lifestyle shoes, apparel and accessories.

The scanner is the first stop worth making. The official store page lists a 3D foot scanner among its in-store services, built to help you find the right shoe before you start pulling boxes. Ask for a scan even if you think you know your size, because New Balance sells several models in multiple widths, and a width change often matters more than half a size.

Once you have numbers, a staff member can bring out running models in the right width and let you test them on the floor. The remodel split the store into dedicated performance and lifestyle areas, so tell staff early whether you are shopping for daily miles or everyday wear. Runners should bring the socks they train in, since thin dress socks change how a shoe fits.

The detail most visitors miss is the trade-in program. According to the store page, you can trade in New Balance shoes for a voucher worth up to 25 percent of the original MSRP on accepted items, to use toward your next purchase. That turns a worn pair of 990s or running trainers into a discount, so bring them in a bag instead of throwing them away at home.

The store also handles pick-up in store for online orders, and it accepts web returns in new condition within 45 days of shipment. That makes it useful even if you shop online: order two sizes, pick them up on Fifth Avenue, and return the one that does not fit on the spot. An honest note is that this flagship carries New Balance only, so if you want to compare brands side by side, plan a second stop.

The middle of the remodeled store is an open area that New Balance says will keep evolving to highlight collaborations, events, launches and activations. That is where any new release or partner capsule will sit, so check it first if you are hunting a specific drop. When nothing is launching, the hub is a calmer space to sit and lace up while staff pull boxes from the back.

The store sits in a dense office district, so plan around the lunch hour if you want unhurried attention, and come before a race season rather than the week of it. If the store is crowded, the New Balance Run Hub on West 57th Street is a running-focused alternative uptown, and the New Balance SoHo store on Broadway is a shorter subway ride south.

The official hours are Monday to Saturday from 10:00 AM to 8:00 PM and Sunday from 11:00 AM to 7:00 PM. Holiday dates are listed separately on the store page, and the November listings already follow the regular pattern. The quietest window is mid-morning on a weekday, before the lunch crowd. Saturday afternoons along Fifth Avenue are the busiest time for every shop on the block.

If you are short on time, ask for the scan as soon as you walk in, before you browse anything else. Skip the apparel walls until you have settled on a shoe, because trying several widths and models is the part that takes the longest, and the walls will still be there when you are done. Leave at least half an hour for a proper running fitting.

From the door, walk three blocks north on Fifth Avenue to the Flatiron Building at 23rd Street, then cross into Madison Square Park, where the Shake Shack kiosk started in 2004. It is the easiest way to break in a new pair on flat paths. Union Square is about six blocks south if you would rather browse the Greenmarket on market days or continue shopping on Broadway.

The 23rd Street station on the R and W lines is the closest subway, and 14th Street–Union Square is a longer walk with more train options. The 6 train stops at 23rd Street on Park Avenue South, about five minutes east. Eataly Flatiron on Fifth Avenue near 23rd Street is a reliable place to sit down for lunch after a fitting.

New Balance Flatiron Flagship is at 150 5th Avenue, New York, NY 10011. Hours are Monday to Saturday 10:00 AM to 8:00 PM and Sunday 11:00 AM to 7:00 PM. Services include a 3D foot scanner, trade-ins, pick-up in store and web returns within 45 days of shipment.

Bring old New Balance shoes for trade-in credit, ask for a scan before trying pairs, and wear your training socks. Ask Karpo in the Karpo APP to plan a Flatiron afternoon that pairs your fitting with lunch near Madison Square Park.
