Eliminate torsional vibrations to smooth out your RPM's for a quieter, smoother running engine that also results in a broader powerband and more overall power.Proudly made in the U.S.A.
Each time the air/fuel mixture inside a cylinder is ignited, the combustion that occurs creates a torque spike that is applied to the crankshaft through the piston and rod. This torque spike is so severe that it not only turns the crankshaft, it actually twists the crankshaft ahead of its normal rotation and then the crankshaft rebounds. This twisting action is known as torsional vibration. When these torque spikes and forces get into phase with the natural frequency, critical torsional harmonic vibrations occur and can be seriously destructive to the bearings and the crankshaft. Dampers are designed to control those destructive vibrations.

Amazing
Size: 7.5-8.5 Women/6-7 Men, Color: Khaki
These slides are so good! First off, the price is insanely good for such great, long lasting slippers! I ordered the khaki color and it was a nice tan color that elevates every look, whether comfy or more casual. These are so comfortable and also flexible but without breaking which is amazing! The material is soft and perfect for everyone.

Walking on Pillows!
Size: 9-10 Women/7.5-8.5 Men, Color: Dark Blue
These slides are like walking on pillows! This is my second pair, and I wish I could wear them everywhere. They are beyond comfortable. They also look nice on your feet. They are well-made, and I know they will last a long time. I have had one pair for over a year.

So comfortable
Size: 10.5-11.5 Women/9-10 Men, Color: Black
They're so soft to wear! I needed something to wear when it's hot out. These work great and they feel durable! They also clean up easy if i choose to wear them outside. I bought my daughter a pair as well. I think they fit true to the size. I am a size 7-7 1/2 and ordered 7-8.

Size Up!
Size: 9-10 Women/7.5-8.5 Men, Color: Chocolate, Size: 9-10 Women/7.5-8.5 Men, Color: Chocolate
These are very comfortable! My only issue is that I'm a size 9, so I ordered the womens 9-10 and they are *almost* too small. My heel really wants to come out the back. I know the description says to size up, so you really should lol. They are also narrow, as I have wide feet! I will still wear them, just not if I have to walk too much

No more stubbed toes!
This is a very comfortable slip on shower sandal. The bowl design that makes it protect your toes and feet works like a champ! No more stubed toes !! They wore great to prevent that. And they have great traction in smooth wet surfaces. Even with soap on them.
Comfortable fit..
I would buy this product again. Thanks
