Racing Rotary 10W-30Rotary engines do not lubricate like piston engines. The apex seals, eccentric shaft bearings, and front stationary gear all have demands that general purpose oils do not address correctly. Idemitsu Racing Rotary was formulated specifically for this. Use 10W 30 during colder months or in regions with traditional winter temperatures. Switch to 20W 50 when ambient temperatures are consistently above freezing. Formula Fully synthetic, advanced Molybdenum

Perfect thickness and soft feel.
Size: 6-10, Color: Halo Gray/Assorted
Why did you pick this product vs others?: Love theses socks.  It's hard to find socks which won't get pulled down by athletic shoes.  These stay put.

Comfy, great quality
Size: 6-10, Color: White
I’ve had these for quite a while now. They are holding up very well as i wear them a lot for work (coaching). They are very cushiony and most importantly, they do not slip! I would compare these to Bombas but at a significantly better price point.

My favorite socks now!
Size: Medium, Color: Deep Sea/Breaker Blue/Electro Pink
I love socks! And these are quickly becoming my favorites! They do not slide down into your shoe no matter if you are working out or just wearing them for normal everyday use. The price is a little higher than I would normally pay for 3 pair of socks, but after wearing these for a few weeks, I think the quality and comfortability of these socks is well worth the money.
