Question: How much compression? 15,20, 30 hg ?
Document: I dislike how Zensah will not exactly say what is the mmHg compression of their products. I suspect because throughout the socks/sleeves there are different levels of compression and they don't want to give away trade secrets.I ordered these because I have painful varicose veins and wanted these for gym use. These do not provide medical level support. Everyone will be different in their support needs. However, if you are seeking a certain compression level I am guessing these provide 15-20 mmHg.
I have low blood pressure and POTS, and these are fantastic. I'm much less dizzy when I wear them and I'm able to do more. These are much more useful for me than the regular Zensah stockings. My doctor recommended these and she was so right, they are so much better than compression stockings. If you're looking for compression for your blood pressure, these are FANTASTIC! I'm going to buy two more pairs.
Its much better than the regular version. the only downside is it takes a few minutes to put it on. other than that, great product.
I'm 5'5 and leg varies from 14.5 to 15&#34; circumference. The womens medium fit great and is very comfortable. I wear them all day.
I ordered these in XL after looking at the sizing suggestions. While I am definitely not fat (I'm going off of BMI here), I have rather large calves, and these made my legs look like sausages (had muffin tops at the top and bottom of the sleeves... not the look I'm really going for.) They did their job, though, and made my shin splints/calf tears heal much more quickly and made it much easier to walk and run during the healing process.
I only wished to company would be clearer about the level of compression.
Very good compression and very well made product. I would recommend them if you want a well made sleeve. I have very large calves and the large size worked for me.
I have shin splint issues, so I ordered these to use while half marathon training. I found the compression helped my shin splints, but hurt my calf muscles when running. I stopped using them for running to avoid this issue. That said, I put them on after my half marathon and my legs were so happy! I walked 10 miles after my half and felt great! Highly recommend for recovery.
I purchased these after trying Zensah's regular sleeves. The regular sleeves fixed my shin splints after increasing my run distance by 2 miles. I used the ultra compression for some training and for the race (Spartan Sprint, PA). It took place on a ski mountain in Mid July. When I was done, I had almost no soreness in my legs. My legs took a pounding for about 2 hours, but I felt great after. Next year I will try compression shorts or thigh sleeves.
This was a Christmas gift for my husband. He dropped hints that he needed support for his legs and that he also needed some running gear that would make him stand out since he runs at different times during the day. I thought that this would meet both requirements.
Answer: yes
