Wavetrac Differentials: Modern Engineering for Superior Performance Designed from a clean sheet, the new Wavetrac Differential brings current gear technology to the market. Internally, its gear tooth forms are optimized for strength and improved oil film retention over competitive designs. Our gear package is smaller, reducing overall mass, yet more durable. Attention was also paid to the side gear/axle interface, putting as much material thickness as possible in this critical area - most important when power levels get high. Wavetrac differentials are state-of-the-art helical gear differentials designed, developed, and manufactured in the USA by Autotech Driveline. The Wavetrac Differential is the only torque biasing differential on the market with patented technology that mitigates wheelspin when an unloaded wheel condition arises. During zero axle load conditions, the Wavetrac cam device acts to create internal load, maintaining drive on the gripping wheel instead of acting like an open diff (and going nowhere!). Each Wavetrac Differential is crafted from the highest quality materials available. The internal gears are made from high strength 9310 alloy steel. The diff bodies are machined from case-hardened steel billet. To complete the package, every Wavetrac differential is built exclusively using high quality, high strength fasteners from ARP, the world leader in fasteners. All Wavetrac differentials include a transferable, Limited Lifetime Warranty.

Size down. Thin soles are cold.
Size: Small, Color: Light Grey Ragg Wool
The ragg wool is warm and they seem well made.
The foot sizing is very long. I'm a 7.5 to 8 always. The choice was 6-7 or 8-9. The 8-9 is more than 2 inches too long. I'm afraid they will cause a fall. Also know that the cushioning is not as pictured. It is only half the depth of the leather sides. When you stand on anything but carpets, you feel the cold floor. This is all due to the gravity on earth.

Best slippers, beware Sizes may be off.
Size: Medium, Color: Charcoal Ragg Wool
I LOVE these sock moccasins shoes or whatever they are.
I purchased 2 pair in different colors and the upper sock material was a significantly different material in its weave density and stretchyness. (blue more thin and stretchy than grey). I wear blue ones indoors, and the grey ones stay in the car for long car trips. Sizing: both pair I bought say 7-9mens 9-10women -- In how they actually fit they are 9-10 mens. The soles are leather with a thin bit of soft foam, in winter I can walk around in snow in them and the cold doesnt get through. Not that you should walk in snow with them since the leather is like a suede so it gets gross. You can put them through the washing machine and it makes them look good as new.

Is this a joke slipper?
Size: Large, Color: Charcoal Ragg Wool
Bought size large (men’s 9-10) this past year for my husband for Christmas. These are not made to fit a human being unless it is a severely skinny person with very very long feet. The feet are too big for him but the ankles are so narrow he can’t put them on, and my husband is actually very lean, he teaches martial arts for a living 6 days a week. I don’t believe I’ve ever seen a person in my entire life who simultaneously has long enough feet combined with skinny enough legs to fit these slippers. For a laugh we got our skinniest female friend to try them on and she could just barely squeeze her legs into them. I think she described it as “squeezing her skin off of her legs” or something like that, and then of course the feet were comically huge for her because she is so petite. We never got around to returning them and I just found them last night and remembered the whole incident. I tried to fit my forearm inside them but could not fit much past the wrist because they were too tight and I had a good laugh. I think I might cut them up and use the pieces to patch his old slippers that actually fit. To be fair we actually got a lot of laughs out of the product so it wasn’t a total waste. Buy them as a joke or save your money.

Great slippers.
Size: 14-15 Women/12-13 Men, Color: Light Grey Ragg Wool
They're great slippers. Literally my whole family, nuclear and extended, wears them. This is the 3rd pair I've bought. I usually wear a size 12, but these are a little big. Ill be washing them in hot water and drying them in...well...the dryer to see if they shrink. I can't recommend these slippers enough.
