Inventory management for Shopify shoe stores

The inventory problems shoe stores run into

• Size curve complexity. a single style in 3 colors and 10 sizes is 30 SKUs, and demand is not even across sizes, so you need per-size reorder points, not one number per style.
• Broken size runs. when the middle sizes (8, 9, 10) sell out first, the style looks "in stock" on paper but is effectively dead stock for most customers.
• Seasonal and category splits. boots, sandals, and school shoes each have their own selling window, so a single reorder calendar across your whole catalog does not work.
• Wholesale minimums by style, not SKU. suppliers often set a minimum total pairs per style or per size run, which can force you to buy sizes you don't need to hit the minimum.
• Long overseas production lead times. many shoe suppliers manufacture to order or ship from overseas factories, so lead times are long and unforgiving of late reordering.

Seasonality and demand

Shoe demand usually comes in clear waves: boots and cold-weather styles in fall, sandals and lighter shoes in spring and summer, and a back-to-school bump for kids' and casual styles. Each wave needs its own order-by date, worked backward from when you want stock on the floor, not when you place the order. Because lead times for shoes can run long, especially from overseas factories, you often need to commit to a season's buy well before the season starts, based on last year's size curve and this year's trend. Build in extra safety days around these peaks since a stockout on a size 8 in October means a lost sale, not a delayed one.

Suppliers, lead times and minimums

Shoe suppliers fall into a few types: domestic distributors holding existing stock, overseas factories that manufacture to order, and branded wholesalers who sell set size runs. Domestic distributors can often turn around an order faster, while overseas manufacturing often takes several weeks or more and may require committing to a production run in advance. MOQs are commonly set per style as a minimum number of pairs or a full size run (one pair in each size), not a flat unit count, so your order quantities need to respect the size curve, not just a total number.

Worked example

Say you sell a canvas sneaker in size 9, your best-selling size, at an average of 1.2 pairs a day. Your supplier's lead time is 20 days and you keep 5 safety days, so your reorder point is 1.2 x (20 + 5) = 30 pairs. You currently have 18 pairs on hand and 0 on order. If you want 35 days of cover, order quantity = 1.2 x (20 + 35) - (18 + 0) = 66 - 18 = 48 pairs, which you'd round up to the nearest case pack your supplier sells, say 50 pairs.

Try it with your own numbers in the reorder point calculator, or size your buffer with the safety stock calculator.

A simple system to start this week

1. List every style as separate SKUs by color and size so forecasting works at the size level, not the style level.
2. Set each supplier's lead time accurately, including extra time for overseas manufacturing versus domestic restock.
3. Add safety days around your known seasonal peaks like back-to-school or holiday boot season.
4. Check that suggested order quantities respect your supplier's size-run or per-style minimums before approving.
5. Review your weekly reorder email for styles with broken size runs, not just low total stock.
6. Confirm received pairs against the packing slip, since partial shipments on size runs are common.

How SteadyShelf fits shoe stores

SteadyShelf forecasts and sets reorder points per SKU, so it can track each size separately and tell you when a specific size is about to run out, not just the style overall. It rounds suggested quantities to case packs and minimums, which helps with size-run MOQs, and it drafts and emails the PO once you approve it. It does not track lot or expiry dates, which does not usually matter for shoes, and it does not handle multi-location transfers, so if you stock multiple store locations you will still need to move inventory between them yourself.

$29/month flat, unlimited products and suppliers, 30-day free trial.

SteadyShelf is launching on the Shopify App Store. Join early access to get the install link first.
