Built Different: 2 Years of R&D and Lab Testing

Made by a PhD scientist, using the same method museums trust to protect rare items — lab-tested to simulate years of aging, proving 3X less yellowing and crumbling.

CapSole (Lab-Tested)
3X Less Yellowing, Crumbling, & Aging
Preservative Fights Oxidation

Preservative Fights Oxidation

Our preservative replaces the oxygen inside the bag. It slows yellowing and aging — instead of sealing oxygen in.

Blocks Oxygen, Moisture, & Light

Frequently Asked Questions

Does CapSole really work?

Yes. CapSole creates an airtight, oxygen-free barrier that blocks the three biggest drivers of sneaker aging: oxygen, moisture, and light. In lab testing, sneakers preserved with CapSole showed 3X less yellowing and aging than sneakers left unprotected. Oxidation and moisture loss are the same underlying forces behind sole separation and material breakdown — which is why reducing exposure protects more than just color.

Is CapSole worth it?

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.

What causes sneakers to yellow and crumble?

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.

How is CapSole different from silica packets or storage bins?

Silica only absorbs moisture. Bins and boxes mostly block dust and some light. CapSole is a full preservation system — an airtight, oxygen-free seal paired with a preservative cartridge, built to protect against all three: oxygen, moisture, and light. It's the difference between storage and preservation.

Can I still wear my sneakers?Can I still wear my sneakers?

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.

What sneakers can I use CapSole with?

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.

How long does the preservative cartridge last?

Each cartridge is designed to preserve one pair of sneakers inside a sealed CapSole bag. For long-term storage, we recommend replacing the cartridge everyĀ 6–12 months, or sooner if the bag has been opened frequently.

Will CapSole stop yellowing completely?

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.

Can CapSole restore sneakers that are already yellowed or crumbling?

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.

Does CapSole come with a 1-Year Money-Back Guarantee?

We stand behind every CapSole purchase with ourĀ 1-Year Money-Back Guarantee. If you're not satisfied, contact our customer support team within one year of purchase, and we'll make it right.
