Short answer
The New Balance 550 runs snug, so most buyers should start by considering a half size up. The brand's own guidance splits by gender: the men's page says the shoe fits as expected for most people, while the women's page says most people go down half a UK size.

Fit Notes
- Nike Dunk Low
- The Dunk Low is a snug leather low-top most buyers wear true to size, with a firm ride and little stretch. The 550 follows the same script with a stiffer opening act and a slightly tighter toe box. Dunk wearers who take their normal size can start there in the 550, but anyone who sizes up in Dunks for width should do the same here.
- Nike Air Force 1
- Nike tells Air Force 1 shoppers to size down half because that shoe runs large, while the 550 runs snug. Do not carry your AF1 size across. A size 10 AF1 owner usually measures closer to 9.5, which means taking 10 or 10.5 in the 550 depending on width. Use your measured size, then add the half if your toes run close.
- New Balance 530
- Our 530 review calls that shoe true to size for narrow to average feet with a snug structured midfoot. The 550 is cut from similar cloth but stiffer out of the box, with a tighter toe box that demands break-in. Take the same size in both if your feet run narrow; take the half up in the 550 if the 530 already feels snug.
- Adidas Samba OG
- Our Samba OG review describes true-to-size length with severe narrowness and leather that needs breaking in. The 550 tells the same story with a higher collar and a harder sole. Samba wearers who sized up for width should take the half up in the 550 too; those who tolerate the Samba squeeze can start true to size.
Sizing FAQ
Do New Balance 550 run true to size?
Close, but on the snug side. The men's page says as expected, the women's page suggests going down half a UK size, and buyers mostly report a narrow, tight fit. Narrow feet usually fit true to size; average feet often take a half size up. If your toes touch the front, size up.
Are New Balance 550 good for wide feet?
No. The midfoot and toe box run narrow with no wide version available. Wide-footed owners report pinching, especially at the base of the big toe, and usually return them. The 530 in wide or a roomier court shoe fits far better.
Do New Balance 550 stretch out?
Yes, meaningfully. The leather upper molds to the foot over days of wear, and owners say the painful first hour gives way to real comfort. The width gains are modest, though: break-in fixes stiffness, not a truly short or narrow fit. Buy the size that fits nearly right on day one.
