Naturalizer is usually a true-to-size starting point, but width and shoe shape can change the feel. This guide covers its size chart, model-specific fit notes, and what to measure for sneakers and boots.

Naturalizer Sizing: Does Naturalizer Run Small, Big or True to Size?
Start with the larger foot
Naturalizer is usually a true-to-size starting point, but its chart and style-specific notes matter more than the brand name alone. If you are searching for the naturalizer size chart, it spans U.S. sizes 4 to 13, half sizes through 10.5, and Narrow, Medium, Wide and Extra Wide columns; the company asks shoppers to measure both feet and use the larger one. Naturalizer's Fit Hub describes a range from 5M to 12XW and says the brand fit-checked tall boots on more than 100 women. That broad range is the useful part: the shoe offers room to compare width, while the final fit still varies by shape. Nordstrom's Behold Mary Jane Flat, Mavis Bow Pointed Toe Pump and Rumi Slingback Bit Loafer Pump each say true to size, and Macy's Flexy Slip-On Ballet Flat does too. But one Naturalizer size is not a guarantee: reviewers flag narrow toes in some flats and an occasionally loose or long fit in certain styles. Founded in 1927 around shoes designed for women's foot contours, the brand's comfort promise is a real point of view, not a sizing algorithm. My rule: begin with the larger-foot measurement, choose the width deliberately, and let reviews on the exact style overrule habit.
Flats are the simplest test
Flats are the cleanest way to start the comparison. Ava Ballet Flat is labeled true to size by the brand and comes in medium and wide, but Nordstrom's customer notes include some fit complaints; I would try it with the sock or hosiery you usually wear. Behold Mary Jane Flat is also true to size, has medium and wide options, and adds a hook-and-loop strap with a cushioned REZORB footbed, which gives a little adjustability across the instep. Macy's Flexy Slip-On Ballet Flat is marked true to size, offers M and W, and uses a rounded toe with a padded collar. The Kelly-Ballet Square Toe Flats have a leather upper and N5 Contoursock padding; the product page says true to size, though some customer reviews find the toe snug. My practical short list: start with Behold if you want a strap to steady your foot, and choose wide width only if width, not length, is what you need.
Pumps and straps call for a closer read
Mavis Bow Pointed Toe Pump and Rumi Slingback Bit Loafer Pump are the strongest starting points if you want a heel without losing the fit notes: both are marked true to size and sold in medium and wide. Mavis has a 1.75-inch heel, pointed toe and cushioned footbed; Rumi uses an adjustable slingback, a 2-inch heel and Contour+ cushioning. The pointed toe is the variable to check in Mavis, while the adjustable strap is the useful detail on Rumi. Macy's Yasmin Mary Jane Pumps add a 2.5-inch block heel and adjustable ankle strap, but the page does not provide a specific fit recommendation, so try the closure and toe box rather than assuming. Jayla Mid-Heel Square Toe Slingback Pumps are labeled true to size and have a low 1.5-inch heel with REZORB cushioning, yet customer reviews also mention a loose back strap or a larger-feeling fit. Practical tip: walk around at home before wearing a slingback out, and do not size up just to solve a narrow toe without checking the heel hold.
Fit from everyday shoes to boots
On casual days, Marianne Slip-On Sneaker is the clearest comfort-first choice: Nordstrom lists its N5 Contour footbed, removable insole and dual elastic gores, with a true-to-size note. Macy's Cami Lace-Up Sneakers give you laces to fine-tune the instep and a suede upper; the product details list a Future Foam footbed. Shay Lace Up Sneaker on Naturalizer's own site is labeled true to size, spans narrow through extra wide, and is currently marked final sale, so check the chart before ordering. For Eloy Zip Boots, foot length is only half the job: Macy's gives a 6.46-inch shaft and 9.45-inch circumference on the regular-calf version. Naturalizer's size chart notes that boot calf measurements are product-specific, and the Fit Hub tells you to use the measurement of the larger calf. Practical tip: measure in the socks you plan to wear and compare calf width before committing.
