Yes. CapSole combines a pod made with multiple airtight barrier layers that limit exposure to oxygen, moisture, and light with a preservative that replaces the air inside. During filling, the existing air escapes through the outlet valve. Closing the valve seals the protective environment around your sneakers. Together, these mechanisms help slow oxidation and hydrolysis—processes that contribute to yellowing, crumbling, adhesive deterioration, and sole separation. In lab testing, sneakers preserved with CapSole showed 3X less yellowing and aging than unprotected sneakers, helping protect more than just their color.

If your rotation includes pairs worth $200, $500, or $1,000+, preservation is cheap insurance. Replacing a pair that's yellowed or broken down almost always costs more than protecting it would have. The rotation doesn't lie — the pairs you keep sealed are the ones that hold their value.

Sneakers age even sitting in the box or on feet. Oxygen, moisture, UV light, and heat slowly break down rubber, foam, adhesives, and clear soles over time. CapSole's sealed environment cuts off that exposure, so your pairs stay closer to day-one condition, longer.

CapSole combines two forms of protection: a pod made with multiple airtight barrier layers that limit outside oxygen and moisture, and a preservative that replaces the air inside. Together, they help slow oxidation and hydrolysis—the processes that contribute to yellowing and crumbling. Shoeboxes and standard display cases generally allow air and moisture to circulate. Typical vacuum bags and shrink wrap can allow oxygen and moisture to seep back in over time, and neither replaces the air inside with a preservative. Vacuum bags also compress around your sneakers, which can put pressure on their shape. CapSole protects the environment around your sneakers while preserving their shape. Its pods are reusable, so you can wear your sneakers whenever you want, then reseal and refill them for protection between wears.

Absolutely — CapSole is built for wearers, not just collectors. Wear when you want. Let them dry fully, then reseal in the bag. Protect Between Wears is the whole point.

Virtually anything in your rotation — Jordan, Nike, Adidas, New Balance, ASICS, Puma, Converse, and more. Compatible with leather, suede, nubuck, mesh, canvas, knit, and patent leather. Grails and daily rotation pairs alike.

Each cartridge provides approximately two fills, depending on how much preservative you release. Once your CapSole pod is filled and sealed, nothing needs to be replenished until the pod is opened—even during long-term storage. Refill it after opening and resealing, and replace the cartridge only when it is empty.

No product can stop aging entirely — and we won't tell you otherwise. What CapSole does is significantly slow it. Lab testing showed 3X less yellowing versus unprotected pairs, which for a lot of collectors is the difference between a shelf pair and a museum pair.

No — CapSole prevents future damage, it doesn't reverse damage already done. The earlier you start, the more of the sneaker's original condition you lock in.
