I know, again. I lurked around and thought I bought the right size shin guards found here: http://www.muaythaifactory.com/muay-thai-equipment.asp?ProductID=TKSGPGL-BK-RD (fast shipping and great service btw) I bought a size large, they seem too big. The straps barely lock onto their velcro as I have to pull them so snug. The top of the pads hit slight into my knee cap. I have added some pics, please excuse my shitty photography My shins measure about 14.5" and my calves about 14.5" around the largest size. I wear size 11 shoes. `I'm about 5'11" 165lbs, 29 inch inseam I know all signs point that I should probably exchange it for a medium, right? thanks!
