Background

The CD300 receptor family members are a group of molecules that modulate a variety of immune cell processes. The CD300 receptor family consists of members with activating and inhibitory capabilities mainly expressed on the surface of immune cells. LMIR5, also known as CD300b, CD300LB, CLM-7, and IREM-3, is a glycoprotein member of the immunoglobulin superfamily. Human LMIR5 consists of a 134 amino acid (aa) extracellular domain (ECD) with one Ig-like V-type domain, a 21 amino acid (aa) transmembrane segment, and a 29 aa cytoplasmic domain. Studies have shown that CD300b recognizes PS as a ligand and regulates phagocytosis of apoptotic cells through DAP12 signaling pathway.

Too small
Material Type: Gray - 3 Pairs, Size: X-Large
Too tight! Even size large used for a man with smaller feet is too tight. Also, no instructions for use or care.

Good fit
Material Type: Black - 3 Pairs, Size: X-Large
My husband just started using these and they feel comfortable. Hasn't used them long enough to see if his heels are better. He has a high arch so I bought him the XL and they fit perfectly.

No more painful cracked heels! These really do work!
Material Type: Black - 3 Pairs, Size: X-Large
These really do work well. This is one of the first winters that I have not experienced painful, cracked heels. They are long lasting, and definitely make my heels smoother and softer after wearing them. For the first few times wearing them I simply went with the moisturizer embedded in them. After a few uses I then covered my heels with Aquaphor Advanced Therapy Healing Ointment. This worked even better, and I would recommend it. I am very glad I bought these. Of note, I have really big feet that are quite wide and the XL are a little snug but not uncomfortably so. I use them overnight, but also have worn them under socks and they work fine.

Wonderful for dry feet
Material Type: Black - 3 Pairs, Size: X-Large
I have been dealing with dry skin and problems with the heel of my foot, so I thought I would give these a try. I am so glad I did. They moisturize beautifully. A must is you are having trouble with your feet.
