Nordstrom

Nordstrom is one of the places with the largest array of single and mismatched-size shoes — as long as Nordstrom is the seller, you can choose any brand and style you’d like.
How to Order: To order a single shoe, customers must call Nordstrom’s customer service team, who can check current single-shoe availability in your size and place the order over the phone. Choices may be slightly limited since options depend on what is available at the time you’re ordering. Because Nordstrom’s single-shoe inventory is created from split size returns, availability is constantly changing. If you don’t find what you’re looking for, it’s worth checking back — Nordstrom updates its single-shoe inventory every Monday, meaning new styles become available weekly.
For split-size shoes, you can either call customer care, work with a salesperson in-store, or order online. You’ll purchase two pairs of the same style in your desired sizes, then return the two unwanted shoes once the order arrives. Nordstrom will issue a refund for the returned shoes.
Requirements and Restrictions: For the split-shoe program, the only requirement is that the shoe must be sold and shipped by Nordstrom.com. As long as Nordstrom is the seller, you can choose from any brand and style you’d like. Both single and split-size shoes are available in men’s, women’s, and kids’ sizes.
For split-size pairs, Nordstrom’s website states: “To qualify, shoe sizes must be at least one and a half sizes different, at least one size and one width different, or two widths different.” However, customer service representatives have noted they may still be able to accommodate customers outside those parameters on a case-by-case basis.
Pricing: A single shoe costs $26 plus a flat shipping rate of $9, regardless of which shoe you’re buying. A split-size pair will ultimately cost the same as a matched pair once the return of the unwanted shoes is complete.
BILLY Footwear

BILLY Footwear offers a broad assortment of shoe styles for both adults and children. Everything they make is created with the goal of making footwear accessible to a wider range of people, regardless of their needs or abilities. The brand offers wheelchair-friendly, easy-on-and-off, and sensory-friendly styles, among others designed with different needs in mind. Their signature design features a zipper that wraps around the side and toe, allowing the upper to open completely and making it significantly easier to slip your foot into the shoe.
How to Order: First, create an account and then reach out to their customer service team to request approval to use the code “SINGLESHOE,” which enables customers to place either a single shoe or split-size order.
For a single shoe, add your desired style to your cart. When you’re ready to check out, apply the code and write a message in the “leave a note” box specifying whether you need the right or left shoe sent to you.
For split-size shoes, the process is the same, except you’ll add two pairs in your desired sizes to the cart. As with the single shoe, apply the code and leave a note specifying which sizes you need for which foot.
Requirements and Restrictions: The only requirement is that you must purchase full-priced shoes, as the code will not apply to sale items. Keep in mind that the code applies to all items in the cart, so if you’re trying to order both a matched-size pair and a single or split-size pair in the same order, it won’t work.
Pricing: If you’re purchasing a single shoe, you won’t pay exactly 50% of the pair price. The discount code reduces the cost by only 30%, meaning a single shoe ultimately costs about 20% more proportionately than purchasing a matched pair.
Ikiki Shoes
Ikiki Shoes sells single shoes starting at $22.95 and maintains a dedicated single-shoe collection on their website, making it one of the more straightforward options for shoppers who need just one shoe without the need to call customer service or request a special code.
