This is a great shoe for serious walkers with issues with pronating.  This is not a pretty shoe by any means but your feet will thank you. I just took up power walking again after many years(3 1/2 to 4 1/2 miles per hour). I tried walking in my brooks running shoes but that didn't work. I have a heel spur and plantar fascia issues.  They shoes are great no heel pain at all. You can also use an orthotic Witt these if needed. If u sure about your size,  the new balance web sight has a size converter where you put in the brand and style of shoe you wear now and it tells what size on new balance to get.  I sized down half a size from an 8 1/2 to an. 8.
