The months on this calendar are ranked by how deep running-shoe promo codes actually run — the share of codes SimplyCodes verified in each month that took 25% off or deeper, pooled across every year on record and re-measured daily. It reads the discount climate across running-shoe brands and the retailers that sell them rather than the price of a single model, since a brand store's code usually applies across its whole catalog.
December is the best month to buy running shoes with a promo code.

Deep-discount share = the share of that month's tracked running shoes promo codes that were 25% off or deeper · bar = that share relative to the strongest month · codes checked = the denominator behind each share · — = fewer than 3 retailers contributed that month, so no share publishes · free ship / free gift = at least one such offer verified in that month.

Methodology
How SimplyCodes verifies codes. Behind every figure in this live data study is the SimplyCodes verification system. Coupon codes are tested at real checkout before they are listed, through three independent layers: daily automated testing, where headless browsers runs headless browsers through real checkout flows and records whether a discount actually applies. A human verification network of 10,000+ verifiers submits screenshot-and-timestamp proof. And a real-time fleet signal, where live checkout outcomes feed back into the engine. The calendar below summarizes that verification history month by month.
How this calendar is built. we group every running shoes promo code SimplyCodes has checked at the running-shoe brands and retailers SimplyCodes tracks by the calendar month it was verified in — so "December" means every December on record, not one year's. For each month we report the share of those codes that carried a discount of 25% off or deeper, alongside the number of codes behind the share. Only percentage-off codes are counted, because fixed-amount offers are not comparable across price points. Percentage claims of 95% or more are excluded as implausible. And a month contributed by fewer than 3 retailers publishes no share at all

Frequently asked questions
When is the best time to buy running shoes?
The calendar above names the strongest month, its share of deep codes, and the date the snapshot was taken. Pooled across every year on record, the late-year window carries the highest share of deep running-shoe codes and the late-winter and mid-spring months carry the lowest, so a pair bought in February comes out of the year's thinnest code pool.
What month are running shoes cheapest?
This study ranks months by discount depth on verified codes, which is not the same as a cheapest-price ranking. Two things move a running shoe's price that no code can show: the model changeover, when last year's version drops to clearance at its own pace per brand, and retailer-specific markdowns that need no code at all. The calendar tells you when the code window is widest across the whole set of sellers: the brands Nike, Adidas, HOKA, Brooks Running, ASICS, On Running, Saucony, New Balance, Under Armour, Altra, Topo Athletic and Salomon, the specialists Road Runner Sports, Running Warehouse, Fleet Feet and Holabird Sports, and the general sellers runners buy from, Zappos, REI and Dick's Sporting Goods.
Does the model changeover beat waiting for a holiday sale?
They are different mechanisms and they do not fire on the same schedule. A changeover discount is specific to one shoe and one brand, and it lands whenever that brand ships its next version. The code window on this calendar is market-wide and repeats by season. If you already know the exact model you want, the changeover usually wins. If you are open on the model, buy in the deeper code months the calendar names.
Does a deep running-shoe discount mean the code will work at checkout?
They are separate questions. Depth is how much a code takes off, and reliability is whether it still applies at checkout — the Health Score (SimplyCodes' 0–100 measure of how likely a code is to work at checkout) on each code covers the second one. This calendar reads depth only, and each brand's or retailer's own SimplyCodes page carries its current working codes.
