I ordered the Matilde LR boots from NM during their addtl 40% off sale, and they've arrived. I ordered them in brown (size 5.5) and black (6) because i didn't know which size I was. I really wanted the brown ones in my true size (6), but it wasn't available. So now I have them here, and I can't tell how they're supposed to fit. The 5.5s are tight around the toes but not uncomfortable, although it will be a fight to get them to fit with jeans tucked in. i can't wiggle my toes in them at all. the 6s are comfortable around the toes and i can wiggle my toes just a little, but there's some heel slippage when i walk. i can't tell which ones i should keep! my mom says the boots will probably stretch over time, but i'm not sure (my frye boots haven't stretched at all). right now, i love both colors so i can go with either. i'm more concerned with comfort. help!!
