Customer Reviews

Comments: I have CW-X Pro Tights and recently purchase the Zoot CompressRx Active Tight. The tights provide great muscle and joint compression including the hips and low back. My calf muscles and knee joints were sore and ached after I took the tights off and I never experienced that with the CW-X tights after a long run. I find it very hard to get the Zoot tights off over my heel. They are hard to put on and position on the body; but so are the CW-X tights. The Zoot tights stay in place when they are on and don't creep down like the CW-X Pro tights do on me. I would purchase these tights again. I have not worn them in hot or warm temps so can't comment on that aspect of their performance. I am 5'3" and 125lbs. and ordered size 1. They fit my body shape perfectly.

Comments: I received the Zoot compression tights yesterday and tried them for a run the first time today 11/3/09. In terms of actual benefit during exercise, I'm not sure what I expect from compression clothing. Per sizing guidelines, I bought the size 2. The tight fits well, as there is no uncomfortable pressure or seam spots. The material is stretchy, but it doesn't stretch a million miles. If you buy the correct size, the tight should stretch just enough to provide moderate compression, not strangling. I run the majority of time on trails, which are mostly hilly. Wearing compression tights on the flat portions feels kind of good and when running downhill, these tights are awesome. However, when running up hill, compression tights (not just Zoot, all other brands too) restrict flexibility and greatly inhibit efficient uphill running. I was thinking that the complex weave pattern in these Zoot tights would alleviate the denim pant syndrome I've found with compression leggings. Not the case. Going uphill fast in these tights does not happen. I do like these tights. They fit well and prior to today's run, i wore them with slightly sore quads (not working out, recovery) and they make my legs feel good. I might try another flat run with them, but these tights feel better after a workout then during one. They are slightly warm too, although they don't have thermal fleece. They do feel great in cooler weather. Generally, this is a well made, well thought out product. I'm just not convinced that grater levels of compression can assist my athletic efforts: running 1-4 hours, always trails with hills. That's it. Hope this helps someone.
