These shorts just mould the back bum perfectly. The back has the UPLIFT scrunch bum feature to lift the bum too. The Extended High Rise moulds the waist and can also be worn as a slight foldover.
If you look from the side of these shorts you will see the leg sculpts, ie: raised in the front and drops towards the back, so they don't cut you square like many shorts do. Added bonus is the side keyhole for some further detail.
