These boots are definitely wide calf and fit exactly how I wanted them to.  The only downside is that when you put your phone in the pocket it tends to drag down the boot a little and I'm worried that eventually it's going to stretch out so much that I can't wear them.  For reference I have an iPhone 6S Plus and it does fit snugly with just a snap case on it.  Only the right boot has the pocket so if it gets too bent out of shape they'll be lopsided boots and I definitely won't want to wear them then.

However if you're just looking to put a few cards and some cash in the pockets you'd be perfectly fine.
