adidasMen's Tiro23 League Pants

Size chart on this listing says s-m in the size i need, but there is no option for that when i go to the pants option (i wear 32x30 pants). any ideas?

what's the difference between king and tall ??

What is the inseam lenght of the men's medium. He is 6 ft and 165 lbs

If i just outgrew kids xl (waist 33" x 30 inseam, with thick legs), will this mens small be too tight? though i'm worried the sz medium will be long
