Pinless Universal Design

An ordinary ball type universal join has a structure with a pin type joint. Ko-kens universal joints are connected with mutually engaged hexahedrons. This connection disperses the load across whole outer circumference. The same durability is obtained with this design in comparison to the pin-type.

Nut Grip Technology

Our nut grip sockets are unique to Ko-ken and truly a revolutionary way of approaching this type of socket. Our fastener holds nuts and bolts in place without the use of magnets. Our system is built with a spring ring and ball bearings on opposing flats. When a nut or bolt is in the socket the ball bearings push out on the springs holding the nut/bolt in place. Our nut grip sockets can completely change a mechanics efficiency. If you lose a nut or bolt inside of an engine it can be quiet the headache to retrieve. With nut grip sockets that dilemma is completely eradicated.

My Heels Were in Bad Shape. Like… Really Bad
Color: Gray
These moisturizing heel socks with the gel cushions were honestly a small miracle for me. After recovering from cancer treatments, my skin became extremely dry everywhere, but my heels were the worst. They cracked so deeply they looked like fissures and were even bleeding. I tried lotions and bandages repeatedly with very little progress. A friend suggested I treat my heel like it might have a fungal component, so I applied Lotrimin cream, put these heel socks on, and hoped for the best. Within three days, my heels were fully healed. I completed a 7-day routine, and my feet have never been softer. The silicone gel cushion is comfortable, soothing, and stays in place. I loved it so much that I still treat myself about once a week, even though I really don’t need to anymore. They are also washable. I hand-washed mine in the sink and let them air dry, and they came out looking brand new. If your heels are cracked, painful, or need serious care, I highly recommend these.

Ehh. Not for me.
Color: Gray
Foot slides when walking in them. The fit was tighter than lead to believe. It did hold the moisture in but the silicone patch is small

Healed cracked feet!
Color: Gray
These moisturizing heel socks are great for dry, cracked heels. They’re soft, comfortable, and easy to wear around the house or overnight. I like that the silicone/gel part helps lock in moisture, especially when paired with foot cream or lotion. They fit well without feeling too tight, and having 4 pairs is really convenient. After using them consistently, my heels felt softer and smoother. Great little self-care item, especially if you’re on your feet a lot or struggle with dry skin.

Great stretch.
Color: Gray
My husband has diabetes and these work great on his heels. I was worried they would be too small, he wears a size 12 shoe and they fit great!
