Helen
I love love my Step One boxers, I wear them for long distance running.
Excellent anti-chafe and moisture-wicking.
G M Woolrych
Was looking for some comfortable underwear for long runs - it's not easy to find boyleg pants for women, so these are perfect. Nice long leg, really soft, and no seams where you don't want them!
Pamela F.
My sons all love these boxers, great quallity and are good for larger thighs from rugby, running and body building!!
Daniel V.
Ran my first LA marathon in these. Design looked great, wicked away sweat very well, and best of all: no chafing!!
Pete B.
Love the quality and the feel. Have tried them out running. PERFECTION!!
Graham A.
Great fit and so comfortable. I wear them while running and they don't chafe at all. I've tried other similar brands and these are definitely the best.
Chris B.
These boxers are the best around, I use mine when I'm powerlifting, running, walking etc.

Fantastic product, bought for long distance running to prevent chaffing. Would highly recommend
