Product Overview

Cobalt tetroxide belongs to transition metal oxides, which are in powder form and generally appear gray black or black in color. Its molecular weight is 240.8, density is 6.11cm2/g, and melting point is 895 ¡ãC At room temperature, cobalt trioxide material is insoluble in water. When the temperature reaches above 900 ¡ãC cobalt trioxide (Co3O4) decomposes into cobalt trioxide (Co2O3) and cobalt oxide (CoO), and the final products will stabilize into CoO. Meanwhile, cobalt trioxide is also a p-type semiconductor and antiferromagnetic material with a bandgap width of 1.5 eV. Co3O4 is a spinel type oxide with a lattice parameter of approximately 0.809nm. There are three methods for preparing cobalt trioxide based on the physical state of the required cobalt source: solid-phase method, gas-phase method, and liquid-phase method.

Great socks / a bit expensive
Size: Large, Color: Black
These may be the Goldilocks of the socks I've tried. They have nearly the same quality as the MUCH pricier Darn Tough Vertex Ultralight Cushion Cool Max socks (also reviewed). They have better quality, and a higher price, than a similar pair of PUMA socks (also reviewed). Pros: Very well made, with no loose stitching, comfortable forefoot and heel cushioning, good ventilation via top mesh, good arch compression, minimal logos and mostly solid color. Cons: Price is a bit on the high side, but better than the Darn Tough socks. I could honestly have made a good case for any of these three (ASICS, PUMA, or Darn Tough), which explains their collective high ratings. I did the top 3 reviews first. When I get a chance, I'll go back and review the average and terrible :) If money is no object, get the Darn Tough Vertex. If you're price sensitive, and willing to compromise a bit on quality, go with the PUMAs, which is what I did. Otherwise, these ASICS are near the same quality as the Darn Tough, but less expensive. Tough decisions :)

They fit perfectly
Size: X-Large, Color: Black
My favorite socks, the fit is great, they are comfortable and they are long enough so it covers my ankles, therefore, they don't rub against my inner shoe.

Great buy.
Size: Medium, Color: Black
These socks have a cool fresh feel to them. I bought new running shoes, Hoka Bondi 9, and they feel great paired up with them. Similar socks in the store were $49. I tried several others brands like Sauchony and 2 other lesser known brands but there was something indescribably different. I purchased another pack immediately.

Comfort
Size: Medium, Color: Black
I have been wearing ASICS socks since forever! As a distance runner, I have worn many others from different companies, and I always come back! Also, i am not a fan of the invisible kind, and ASCIS seems to be the only ones to make the socks that are above the shoe, are durable, comfortable, I have no desire to look elsewhere. Thanks ASICS!
