Best POS Systems for Running Stores

Q: What's the best POS for a running store?

A specialty-retail POS built around size/width matrix inventory, with fast cross-location stock lookup for fittings, sell-through reporting by size for accurate re-buys, and real-time sync across stores and the website. Runit RealTime is built for this; RICS and Lightspeed are also used in run specialty.

Q: Why is matrix inventory so important for a running store?

A running shoe is a grid of sizes and widths, not one product. You need to buy, receive, and read stock across that matrix to see which sizes sell, reorder at the size level, and avoid dead stock in the wrong sizes.

Q: How do I handle constant model transitions?

Use a POS that shows sell-through by size and supports rule-based re-buys and markdowns, so you move out last season's model while allocating the new one across stores by demand. Runit provides size-level reporting plus rule-based distribution the team reviews and commits.

Q: Can associates check other stores' stock during a fitting?

With real-time multi-store inventory, an associate can see stockroom, other-location, and online stock without leaving the customer, turning a missing size into a transfer or online order. Runit keeps one accurate stock picture across stores and the website.

Run specialty store with a wall of running shoes in many sizes and widths

Run specialty lives or dies on fit: the same shoe in a dozen sizes and multiple widths, models that turn over every season, and a selling floor where associates fit customers instead of ringing them up fast. The best POS for a running store handles deep size/width matrix inventory, makes fast model transitions painless, keeps stock accurate across every store and your website in real time, and helps you re-buy the sizes that actually sell. Below: what to look for, how the options compare, and how Runit fits run specialty.

Why running stores are different

A general or ecommerce-first POS treats a shoe as one product with a few variants. Run specialty breaks that model:

Size and width. The same model exists in dozens of size/width combinations, and you need to buy, receive, and read stock across that whole grid — not as a flat list.
Fast model turnover. Brands refresh models constantly, so you’re always transitioning last season’s version out and the new one in, watching sell-through by size.
Fitting-driven selling. The transaction is the end of a fitting, so associates need fast access to what’s in stock, in the back, and at the other store — without leaving the customer.
Online + in-store. Stock has to stay accurate across the floor and the website so you don’t oversell a hard-to-find size.

What to look for in a running store POS

True size/width matrix inventory used everywhere — from purchase orders to receiving to reporting — so you manage the full grid, not flat variants.
Fast lookup across locations so an associate mid-fitting can see stock in the stockroom, other stores, and online instantly.
Rule-based distribution & replenishment — allocate a new model across stores by sell-through and rebalance sizes to where they’ll sell. (You set the rules; the system builds the distribution for your team to review and commit.)
Sell-through reporting by size — see which sizes and widths move so re-buys match real demand instead of guesswork.
Kits & bundles — sell a starter package (shoes, socks, insoles) as a single item while still tracking each component in stock.
Customer marketing, gift cards & loyalty — a deep CRM/marketing connection (like a real Klaviyo integration) and omnichannel gift cards + loyalty that work the same in-store and online.
Flexible payments — card-on-file and pay-over-time options for VIPs and repeat runners.
Ecommerce sync + support — a reliable connection to your online store, and responsive help when a register goes down on a busy Saturday.

RICS is well known in run specialty, and Lightspeed is common too. See our Runit vs RICS vs Teamwork and Runit vs Lightspeed pages for detail.

Built for loyal, community-based runners

Running stores run on regulars — the training group, the race-season crowd, the customer who’s on their fourth pair of the same shoe. Runit’s strengths matter especially here:

Advanced Klaviyo integration (rare in this category)

Runit’s advanced, purchase-driven Klaviyo integration — uncommon among specialty-retail POS systems — syncs real buying behavior so you can reach the right runners: everyone due for a new pair based on mileage since purchase, buyers of a specific brand, or your training-group VIPs. It turns a loyal community into repeat revenue instead of a list you can’t segment.

Flexible, customer-friendly payments

Runit offers secure card-on-file (via Worldpay’s OmniToken, so card data is never stored in Runit or on your network) — ideal for VIPs and for taking secure payment when a runner orders a hard-to-find size from home. And built-in Buy Now, Pay Later lets shoppers spread the cost of higher-ticket purchases like a GPS watch or a season’s worth of gear.

Omnichannel gift cards & loyalty (with 99minds)

Through Runit’s partnership with 99minds, gift cards, loyalty, and promotions work as one system across your stores and your website — not the split setups that trip up so many retailers (a gift card that only works online, a loyalty program that ignores in-store sales, or the reverse). You get physical and digital gift cards redeemable in-store and online, a loyalty program that spans both channels, and automatic promotional gift-card programs you can trigger by a wide range of criteria and date ranges. Popular examples: rewarding total spend over a period once a runner hits set tiers, or “spend $X today and get a $Y gift card” offers — so a race-season push or loyalty tier runs itself.

Frequently asked questions

What’s the best POS for a running store?

The best fit is a specialty-retail POS built around size/width matrix inventory, with fast cross-location stock lookup for fittings, sell-through reporting by size for accurate re-buys, and real-time sync across stores and your website. Runit RealTime is built for this; RICS and Lightspeed are also used in run specialty. Match the system to your store count and how much you rely on size-level reordering and multi-store distribution.

Why is matrix inventory so important for a running store?

Because a running shoe isn’t one product — it’s a grid of sizes and widths. You need to buy, receive, and read stock across that whole matrix so you can see which sizes are selling, reorder at the size level, and avoid dead stock in the wrong sizes. General POS systems that treat variants as a flat list make this painful.

How do I handle constant model transitions?

Use a POS that shows sell-through by size and lets you build rule-based re-buys and markdowns, so you move out last season’s model cleanly while allocating the new one across stores by demand. Runit provides size-level reporting plus rule-based distribution your team reviews and commits.

Can associates check other stores’ stock during a fitting?

They should be able to. A specialty POS with real-time multi-store inventory lets an associate see what’s in the stockroom, at other locations, and online without leaving the customer — so a missing size becomes a transfer or online order instead of a lost sale. Runit keeps one accurate stock picture across every store and the website.

How can a running store keep loyal runners coming back?

Running is community-driven, so retention tools matter. Runit’s advanced Klaviyo integration (rare in this category) lets you target runners by real purchase history — due for a new pair, a specific brand, or training-group VIPs. Flexible payments help too, plus omnichannel gift cards and loyalty (via 99minds) that work the same in-store and online, including automatic promotional gift-card programs by spend tier or date range.
