NatraCure Replacement Gel Packs for Cold Therapy Socks - 4-Piece Set (2 Full-Length, 2 Half-Size) - Blue, Reusable, Extra Ice Packs for Injuries, Pain Relief

They're working well for me. I bought them to have extra cooling for my feet. Sometimes l need to use 2 consecutively and so l keep these in the freezer so l can switch quickly. I will buy them again if they wear out which l don't think will be anytime soon since they are quite sturdy but flexible enough to slide in the sock openings. The cooling lasts for several hours which is important for me. I think they are a good product.

Worked well with the socks to help prevent neuropathy during chemo

Does what it says on the tin. Could be a bit cheaper though.

These were even better quality that then ones that originally came with the sock (Same brand).

I am a small person, the larger pack fits nicely in the small of my back and brings some temporary relief to a low back disc problem. The smaller works well also as my problem is only on one side. I have tried to find a thicker version of the larger one as when sitting it helps to fill the space between the natural curve of the low back and the chair. Also because of the thinness they don’t stay cold long.
