Compatible with SPA Super A, with 1.5mm / 1.5mm and 2mm channels.
Ring thickness:
1st ring 1.5mm - Made of carbon steel, which is 35% more resistant than cast iron and on average 30% lighter. With DLC (Diamond-Like Carbon) treatment, which is the application of carbon particles, whose physical and chemical properties are very close to those of the diamond, providing greater resistance to the material and reducing the friction of the surface, which significantly reduces friction when working against other surfaces.
2nd ring 1.5mm - Made of cast iron.
3rd ring 2.0mm - Manufactured in 3 pieces, which guarantees easy maintenance, better stability in the control of the oil film and improves the oil removal through the piston lubrication holes, as it has a better area for displacing this oil.

About CMD Extreme Pressure lubricants:

When the operation requires extreme pressure, all ordinary lubricants break down and allow metal-to-metal contact with consequent scoring, frictional heat, work and cutting tool damage.

They will not corrode the finest surfaces nor will they mulsify with cooling liquids. But these facts are not the most remarkable feature of CMD lubricants. The truly outstanding property of CMD is its ability to withstand extreme pressures!

CMD EXTREME PRESSURE lubricants are regularly used from 40,000 to 50,000 psi.

        They work!!
        Color: Fuzzy Slate Gray, Size: Regular, Color: Fuzzy Slate Gray, Size: Regular
        I bought these to replace a very old pair that I originally got at Bed Bath and Beyond like 20+ yrs ago, and the fabric was starting to fray. However, the gel pad inside (at the heel) was still working just fine. Anyway, this new set includes 2 pairs, with a gel pad inside each heel area. Results are truly amazing, I kid you not. You can use them without a moisturizer, but I like to put moisturizer on my heels, then wear these overnight, and in the morning my heels are soft, with no dry skin and NO cracks. I like the fact that these are kind of soft and fuzzy (outside), but I LOVE that they leave your toes exposed and cool (because my heels feel kind of warm from the moisturizer and gel pad). They are of good thickness, and I feel they will last a long time (of course remains to be seen). Highly recommend.

        Perfect for cracked heals ♥️
        Color: Cheetah, Size: Regular, Color: Cheetah, Size: Regular
        These are thick not cheaply made, has a nice texture inside the heal area which I love. I wear them at night after I apply Aquaphor to my heels & while sleeping they are very comfortable. I slipped these guys on & my heels are healing so much faster no more cracked heels for me. 😃 I highly recommend them.

        These socks have saved my heels!
        Color: Fuzzy Slate Gray, Size: Regular
        I really love these socks and how they help my heels to feel. I tend to get large cracks on my heels, and wearing these while I sleep during the summer has saved me a lot of pain. One thing this has disappointed me a bit has been some unraveling of the threads around the top and bottom edges. Doesn't seem to matter how I trim them, the next morning when I wake up there is another hanging thread. Maybe it was just a glitch in the finishing of the batch of socks that I received. I would give them a second chance...this certainly isn't a deal breaker.

        Color: Fuzzy Blue, Size: Regular
        The ZenToes Moisturizing Fuzzy Sleep Socks have been a wonderful addition to my nightly self-care routine. Infused with Vitamin E, olive oil, and jojoba seed oil, these socks are designed to soften and hydrate dry, cracked heels, offering both comfort and skincare benefits. The regular size in blue fits perfectly and adds a soothing touch to my bedtime. One of the features I appreciate most is the intense moisturization these socks provide. The infusion of Vitamin E, olive oil, and jojoba seed oil delivers deep hydration to my feet, effectively softening and healing dry, cracked heels. After just a few nights of wearing these socks, I noticed a significant improvement in the texture and smoothness of my skin. My feet feel much softer and more comfortable, which is a relief after long days on my feet. The fuzzy, cozy design of the socks is another standout feature. They are incredibly soft and comfortable, providing a warm and snug fit that’s perfect for sleep. The plush material feels luxurious against the skin, making it a pleasure to wear them overnight. This added comfort enhances the overall experience, making it easier to stick to a nightly moisturizing routine. The design is practical and thoughtful. The socks fit snugly without being too tight, ensuring they stay in place throughout the night. The regular size is perfect for my feet, and they accommodate a range of foot sizes comfortably. The blue color adds a touch of style and fun, making the socks both functional and visually appealing. The socks are easy to care for, which is a significant advantage. They can be hand-washed or machine-washed on a gentle cycle, and they retain their softness and moisturizing properties even after multiple washes. This durability ensures that the socks continue to provide effective hydration and comfort over time, making them a worthwhile investment for foot care. The moisturizing effect lasts long after I take the socks off in the morning. My feet remain hydrated and smooth throughout the day, reducing the need for additional foot creams or lotions. This lasting effect is a testament to the quality and effectiveness of the ingredients used in the socks. Overall, the ZenToes Moisturizing Fuzzy Sleep Socks have exceeded my expectations. Their combination of deep moisturization, cozy design, practical fit, and easy care makes them an essential addition to any skincare routine. The socks have significantly improved the condition of my feet, providing effective relief for dry, cracked heels and ensuring lasting softness and hydration.

        THESE THINGS SHED BAD!!!!!!!!!
        Color: Pink Strawberries, Size: Regular
        These things shed like you wouldn't believe. They're all over my furniture, my floor, my clothes. I'm finding little pink pieces of sock fluff everywhere and it's annoying. I don't think they did that until after I washed them. So if they don't shed on you right away, just wait, it'll most definitely happen. I returned because I won't where them again.
