A 30-minute category-fit conversation to walk through the new SKU (AIRfeet Recovery Slide, FSA/HSA-eligible), and to determine whether it fits Cardinal's Foot Care / Orthopedic Support catalog. If yes, we handle the SIGIS + UPC + onboarding on our side — you don't take on new vendor risk.
The AIRfeet insole line has shipped through Cardinal for [DURATION — Marshall to confirm]. Terms, logistics, and QC are already in place. Adding a footwear SKU means:
The buyer profile that Cardinal already serves — pharmacies, DME resellers, hospital gift shops, therapy clinics — is the exact same buyer that stocks recovery footwear. OOFOS has proven the retail-shelf demand for recovery slides at $60–80 price points. Nobody has proven them as an FSA/HSA-eligible SKU shipped through medical distribution. We think we can.
| Product | AIRfeet Recovery Slide — therapeutic recovery footwear |
| Construction | Molded EVA · closed-cell · our proprietary EVA cushioning midsole · antimicrobial-treated · water-resistant · durable outsole tread |
| Sizing | Men's US 3–14, Women's US 5–16 (unisex platform, both labels shown) |
| Colorways | Black, White, Navy, Grey (institutional-neutral). School-licensed colorways available via DTC only — not in the Cardinal catalog to keep the medical SKU cleanly positioned. |
| Retail price | $79.99 — same as insole line's price tier |
| HS code | 6402.99 · EVA sandals · same as existing shipments |
| FSA/HSA | SIGIS registered · eligible at checkout — no LMN required for typical use |
| Manufacturer | Riseny Enterprise Co. Ltd (Taichung, Taiwan) — same supplier as insole line |
Materials spec from Riseny · closed-cell EVA density, antimicrobial treatment specification, outsole tread durability testing. Available on request for your category-buyer review.
Same merchant category code as the Relief O2 insole submission. Product classification: therapeutic footwear · foot pain relief. Registered before any Cardinal-facing shelf placement.
17,000+ pairs on the water or in Indianapolis warehouse as of August 2026 (Riseny PO 1000). Additional production runs available on 90-day lead times from Cardinal PO.
Marshall Welton, Managing Member — same contact as the O2 insole line. Single-thread through Cardinal's existing supplier relationship management. No new sales rep, no new escalation path.
This is a first conversation — we're not asking for a PO on the call. Our expectation is a 30-minute category discussion, a decision about whether it's a fit, and — if yes — a light next-step (sample submission, category-buyer intro, or a Q4 pilot proposal). If not a fit, tell us directly so we can invest the time elsewhere.
FSA/HSA account holders spend the majority of their annual balance in November and December (use-it-or-lose-it deadlines). To capture that window, we'd need to be on Cardinal-connected shelves and in Cardinal-catalog searches by mid-October at latest.
If Q4 2026 is unrealistic — which it may be given Cardinal's typical new-SKU onboarding timeline — Q1 2027 is a fallback with a soft-launch approach: DTC only through Q4 2026, learn the FSA/HSA-checkout mechanics, then bring proof-of-concept sales data to the Cardinal conversation in January.
