By far my favorite flight boots, they stay in place and my old man wears them 24/7 with no problem. They are held and long enough to cover the entire tibia. Love love love these boots! New Info: The new top gusset doesn't help them function the way the old versions did. I'm a bit disappointed. Update, these boots are no longer my favorite. The redesign made them as terrifying as other flight boots. I'm really a slacker, can't find a customer service number to talk to someone about this.
