I bought these about a year ago, and they are OK and fit true to size, but the elastic around the leg openings is essentially useless. I have found that http://www.amazon.com/Hanes-4-Pack-Classics-Stretch-Boxer/dp/B00ACIFKDC/ref=cts_ap_2_fbt are a much better buy. A tiny bit more expensive, but the fit is so much better. Just enough compression through the legs that they stay in place and don’t get bunched up even when wearing jeans.
I only wear the Pumas when I run out of clean Hanes.
