Engineered Foam Inserts
Cush Core is an engineered foam insert that sits inside a mountain bike tyre against the rim. It divides the inner volume of the tyre in half, with air underneath the tread as normal, and the Cush Core insert next to the rim. This provides an amazing damper for your tyre, reducing the sudden unwanted spring back that you get from normal pneumatic tyres. Cush Core absorbs shock, protecting your rim from sudden impacts and preventing pinch flats. The support it gives to sidewalls eliminates excessive tyre roll in corners, meaning you no longer have to run heavy, stiff tyres to get the casing stability required for aggressive riding. Cush Core also acts as a mechanical bead lock, anchoring the bead inside the rim so that tyre burping is highly unlikely.

Tubeless Ready And Waterproof
This system is designed to be used with tubeless-ready or tubeless converted mountain bike rims and tyres. The material is also waterproof, compatible with tubeless tyre sealant, and tuned for appropriate rebound feel. Unlike most puncture protection systems, this foam is not destroyed in a single impact. Its ability to withstand repeated impacts without damage is more typical of foams that weigh twice as much. Cush Core inserts are manufactured in Canada to tightly controlled quality standards.

Fully Custom Air Valves For Inserts
A customised tubeless air valve is included with each insert. The air valve allows air to move through the valve without becoming obstructed by the insert.

Unique Patent Pending Shape
Each Cush Core insert is born in a huge aluminium mould, a manufacturing process which allows us to create the unique, patent-pending shape. The shape helps secure the tyre to the rim, and extends well beyond the rim flange to protect against impacts from all angles. Cush Core's special shape also creates the lateral force against the tyre sidewalls that gives Cush Core the cornering stability and calm ride feel it's known for.

Australian Jared Graves Feedback On Cush Core
"Hey guys, just some quick feedback to let you know (and give thanks) that Cush Core definitely saved my race here in Madeira."
- Jared Graves, Team Specialized, Enduro World Series. Protects the rim from sudden impacts, prevents pinch flats . Supports the sidewall - increases cornering ability by eliminating excessive tyre roll . Run lighter tyres . Acts as a mechanical bead lock which stops burping . Acts as a damper to minimise the spring back from impacts to the tyre Includes . 2 Cush Core inserts . 2 customised tubeless air valves . Installation instructions Compatibility 27.5 . Cush Core is compatible with your current tubeless tires and rims . Fits tyre widths 1.8" - 2.4" . Fits rims with internal width 22 - 32mm . If your wheels are not tubeless ready, rim sealing tape will be required . We recommend the use of tubeless tire sealant (such as Stan's) with Cush Core . Installation with certain tire & wheel combinations may require two people - one to work the tire levers, and another to hold the tire bead in the drop centre of the rim. Wire bead downhill tires are most likely to need extra help . 150 grams Durability Cush Core inserts are extremely durable. The foam is engineered to withstand repeated pounding and flexing without degradation. It does not absorb liquid and is not affected by tyre sealant. Service life will depend on your riding frequency, terrain, etc

Very good product
Size: Medium, Color: (001) Black / Black / Pitch Gray
I purchased these to wear inside lowcut slip on casual shoes, I don't particularly like to not wear socks in my shoes for hygienic reasons. Prior to purchasing these socks, all I could find were those made of very light beige hosiery type material , and my slip on shoes would slide around a bit. These are light weight and breathable athletic type material, with a very good gripper strip at the heel. One pair of my slip on casual shoes have a particularly lower cut in the toe area, but the shoe is black and I chose the black color and though I see a hint of the sock there, it matches and does not detract from the look of the casual solid black shoe

They stay out! No more sock wads!
Size: Medium, Color: (100) White / White / Mod Gray
Best no show socks ever made!!!!! I've been struggling for 2 years to find ones that actually stay on your foot, even other national brands, and I just became content wearing my sneakers without socks. They ALWAYS slid down into my show & I ended up walking on a wad of sock until I could fix it...or usually just took them off after a couple of tries. Enter Under Armor!!! They a mid weight, but not very thick & still breathable. They work too by actually staying on your foot! Not once have they slid down into my show!! Very comfortable but they could be a little more affordable.
