Bests & Worsts Reviews from Amazon

I wear the green ones when power walking. It's only been about a week but I can already tell the difference in my thighs and glutes. Today, by accident, I discovered that they're much more comfortable if I wear them with the closure in the back. It doesn't say in the product description, but the grey ribbon at the top and bottom is reflective -- a small but very effective safety feature. I walk along residential streets near my home, so being seen by drivers is important.
