COMP Cams Camshaft CRB3 299Th R7 ThumperDesigned to deliver an aggressive, hard hitting exhaust note at idle, the Thumpr camshaft series from COMP Cams also delivers excellent horsepower gains and a broad torque curve. A perfect choice for muscle cars and street rods, the Thumpr series' early intake valve opening and long exhaust duration create optimum overlap for that race car idle. The Thumpr grinds all require an aftermarket torque converter and lower gear ratio to ensure the drivetrain

Relaxing while watching RJ Decker with my gel socks on!
I love these gel socks. My feet get so messed up working in the yard and swimming in the pool. Just be careful not to slip. Wear while relaxing. Your feet will thank you!!

Disappointing
Not what I was hoping for. I have a size 11 foot, so they fit fine. They are difficult to walk in and if your balance is bad, you run a high risk of falling. I wear mine at night so the majority of the time it is fine until I have to get up in the middle of the night

Serves its purpose
If you can get past the texture of the silicone these will work wonders for your feet. There’s no odor, easy to put on but they are cut small. There’s no moisture it just feels moist because of the silicone. They are very soft and durable.

Dissatisfied
Didn't like the socks at all. The silicone in them made my feet sweat and couldn't wiggle my toes at all.
Gloves were okay, received them with holes between the fingers, only able to wear each twice.
