great pants, unfortunately with little to little feet

Unfortunately, our boys are the feet on the pants to climb something. If the pants in the right size, the feet are too small, I take the pants one size larger legs are too long, yet it slip on the feet. Too bad the pants themselves are great!
Anyway, we used each 3 pants in 2 different sizes, because us the wide, soft waistband liked it so much. Unlike standard tights pinches here nothing!
