Yeah, sorry, I'm not an anatomist so I'm not describing it very well. Inside the work boot, your foot is still able to spread and flex. Women's shoes are a lot narrower and more binding. If you were to wrap an exercise bandage around the entirety of your foot, including your toes, it'd give you a good idea of what I'm talking about. Your foot spreads, contracts, flexes as you need it to, and provided your work boots are the right size, your foot is able to do that inside your boot, even though the boot is heavy. Women's shoes are narrower and don't allow your foot to spread at all, meaning that it's harder to adjust to different surfaces and speeds, and you need to take smaller steps with no side swing.
