About Redline MT90 75w-90. Popular in Nissan, Toyota, Mitsubishi and Mazda manual transmissions and transaxles as well as other selected applications, this is a 75W90 GL-4 Gear Oil that is slightly heavier than REDLINE MTL. Provides excellent protection of gears and synchronisers, and its balanced slipperiness provides a perfect coefficient of friction, allowing easier shifting. IDEAL for Mitsubishi EVO Gearbox.Red Line Transmission Lubricants are designed to provide excellent low-temperature shiftability and improved gear protection at higher temperatures. Efficiency improvements between 1-5% are typical. The synthetic base stocks used have tremendous thermal stability and provide the best film strength available. The unique combination of base stocks and additives allow Red Line transmission oils to carry higher loads compared to petroleum lubricants. The stability of these products allow them to be used for extended periods. MTL® can be used in most manual transmissions and transaxles for both street and racing use unless the manufacturer requires the additional protection of an SAE 90 or the extreme-pressure protection of a GL-5. In those situations the MT 90 (GL-4) or 75W90NS (GL-5) will provide good shiftability and synchro compatibility and extra gear protection. Limited-slip transaxles may require the 75W90 Gear Oil to prevent limited-slip chatter. 75W140NS is designed to help reduce the noise in noisy transmissions and transaxles, while still allowing good low-temperature shiftability. D4 ATF and High-Temp ATF provides the gear protection of a GL-4 gear oil in an automatic transmission fluid, which is far superior to a conventional ATF. This gear protection makes it perfect for lubricating automatic transaxles and high-performance automatic transmissions. The D4 ATF provides the best lowtemperature shiftability. MTL® provides better wear protection in most manual transmissions which call for an ATF which can be very important in racing applications. MTL® provides the lowtemperature properties equivalent to a petroleum ATF. All Red Line transmission lubricants provide excellent synchronizer compatibility.

Does the job but dangerous to walk with!
Does the job but dangerous to walk with: foot is sliding inside the sock if the foot was treated with cream or lotion prior. It is uncomfortable to sleep with but a necessary hurdle to heal your heels!

Does the trick
Bought it with urea cream for my senior dad who was diabetes. Careful with it, it will tear

The really work!
Bought these or a friend with severely dry cracked feet. The change was significant and immediate. They wore them around the house for a day and that night they could already feel the difference.

Fabulously bizarre and effective
These silicone socks have to be the strangest item I have ever ordered from Amazon. However strange they are, I was pleasantly surprised with them.
My order came with two pairs, and I took one pair out to wash before use. I laughed at handling them then because they were a cross between hospital socks and leftover mannequin skin…trippy.
The socks dried fast, so I put on foot lotion and put the socks on. The socks are beige skin tones that cover the entire foot up to the ankle, basically booties.
The silicone is very soft and makes putting on and taking off the socks easy. They are also surprisingly easy to walk around in because the bottoms have grips, again, like hospital socks. I walked on tile, hardwood, and carpet with no slipping. The booties also stayed in place with no issues.
I was concerned my feet would sweat, but that didn't happen. I was able to wear them for 3 hours without sweaty feet.
When I took them off, my feet were a lot more soft than before or if I had used regular socks. For reference, my feet are not terrible, but the skin around my toes is dry and peeling from my picking(gross, I know).
The socks I got are a size large, which worried me because they are big, but the site said for my shoe size (9) that's what I should order, and they were right. They are the perfect size and stretchy for room.
I can't believe how cool and well-thought-out these socks are, on top of working. Honestly, these are among the top 20 favorite items I've ordered from Amazon. They may look incredibly strange, and they are, but they work wonders.

Not well made
I have used these for 2 weeks now and one of them has a hole in the sole...
I won't ever buy them again
