i usually wear pants with a 28'' waist and a 30'' leg, i found some pants i wanna buy on the internet, but its not very descriptive on sizes, the sizes are 24, 26, 28, 30.... does that mean size 30s would be 30 waist AND leg? because 30s would be too big around the waist, but 28s would have way too short legs, so id rather wear a belt than sag my pants. is that a good choice? heres the pants http://skateboarding.activemailorder.com/Catalog/category.aspx?j~&cp=1&ct=4&sc=17&br=105&pr=7546&sk=71259&sm=-1&at=-1&bx=1&px=1&cx=1&bi=0 theres not much detail =/
