So, 9.5 in the PIs today.

No riding up, no bunching, no complaints on fit or comfort. The gusset, if that's even what you'd call it, works fine. The rise is just slightly lower than the Zoots, but still on the high side as shorts go - right at my navel, slightly below the narrowest part of my waist. The waistband is on the firm side, so if that bothers you, it might be an issue. Not as unyielding as CW-X, by any means.

The silicone hem weld didn't want to stay turned up all the way around, once they'd been washed and especially when I put them on. The fold was just ironed in, NOT woven in. The front part stayed turned okay, but the back wanted to roll back down. It didn't give me a rash, but since I started out with them turned up, I didn't run that long and it's a relatively cool day, I can't say the gripper/hem weld wouldn't bother me. But if silicone grippers don't irritate your skin, I wouldn't worry about it.

There's no compression. I definitely couldn't wear a smaller size - these are already a size smaller than PI's size chart says I should wear, they're completely form fitting with no slack fabric anywhere, and the waistband of a smaller size wouldn't go over my hips. They're obviously form fitting enough that they didn't ride up even with the silicone grippers turned up. But they're probably one of the least compressive pairs of short tights I own.

I noticed that the website describes these shorts as having an internal brief. There isn't any, not that I'd want one in short tights anyway.

Temperature regulation - it was a cooler, cloudy day, but VERY humid - rain came through overnight - and although I'd already found out on the clothesline that these shorts do not defy the laws of physics in terms of their black color converting infrared light into heat, they do wick sweat and allow it to evaporate VERY efficiently. I wouldn't hesitate to wear these on a very hot day.

I realized that in my original description I got the pockets backwards. The PIs have the pocket in the small of the back (which again, I don't use pockets, but I did test the accessibility today and it was plenty easy to get into while I was running) - the Zoots have the pockets on the sides of the legs.

Bottom line, I like them well enough, but I'm not sure they're worth $70, and definitely not the $100 MSRP. Still, if it's in your budget and you haven't found anything else you like, I don't think they're *so* overpriced that they're not worth a try.
