I guess it's a matter of opinion. This is an incredibly snug, comfortable boot. The heel cup has extra support in the boot which keeps your heel from sliding up. It also has a material ("cat tongue") that runs up the achilles tendon and calf portion of the liner that keeps both your heel and your sock firmly in place no matter how hard you push it. I disagree with the above poster- I measure exactly 11 US mens shoe size and the 11s are a perfect fit. The toe just brushes the front of the boot while my heel is snugly held in place. Who cares what the inside of the liner looks like?
