Snug Fit
I had read a previous review about these tights, which said they seemed small. Well, when I opened the package the tights looked tiny. I wasn't even going to try them on. Before sending them back, I thought atleast I'll try them. They fit! Amazingly, the tights do stretch and provide compression/ support as reviewed. I'm very pleased with them. I'm approximately 5'8" 135lbs. and ordered a S.

Great product
I am a distance runner and these tights fit and feel great while pounding out the miles.Does seem to aid in reducing muscle fatigue.

Women's Expert Tight-so far so good
I have worn them 2x already. I like the support and the compression effect. I run long distances and actually I feel like with the extra support I am less sore from the workout afterwards. The compression effect on the legs really helps to keep the legs feeling light during the run. Like I said I just got them and am happy with them, hope they are durable. * the picture shows the black pants having gray in them. They don't have any gray, they are completely black.

Great running tights
These are fabulous tights and I love running in them, however they are definitely on the SHORT side - I am 5'7" and wish they were at least 2 inches longer - they look like capris on me and I'm really not that tall.....

Feels great, needs more sizing options
I'm training for my first half marathon and my knees bug me on my longer runs so when I found these at a good deal, I figured I'd try them out. I'm 5'7" and 132-137 so in that grey range on the chart. I opted for the small thinking that to make sure they worked for my knees I didn't want them too loose (the medium can handle up to 50 lbs heavier than me?) They are like putting on some seriously-heavy-duty tights and once they were on they were great. they sit about an inch higher than my ankle socks. Overall the performance is great and they're very comfortable to run it. I would definitely recommend, just wish they were a tiny bit longer.
