some skinny jeans fit like a glove others not so much so the best thing for you to do it take your boots with you and try some one and see if they go over your jeans before you buy them... you could also buy some leggings as they would fit under you boots better. I have knee high boot and not problems getting my jeans in them even boot leg jeans ( just fold them around my leg) but not having thigh high boat I dont know if that would work... I know supre did have legging that looked like jeans you could give them ago too ( dont know how they would look though)... Best of luck, I cant wait until I am back down south to start wearing jeans and boots again, even if BHL think the look is weird, what would he know, the dag, lol
