In reply to The Lemming:
No mine are so massive I get ankle chafing unless I wear the correct undergarments. The only explanantion for a lack of chafing is small genitals and/or puny thighs.
BTW I was a Commando and we were all such strapping specimens that underarmour, vaseline amd talc were all required to prevent chafing, 'going commando' to mean no knicks is inaccurate.
