Brown leather work boots are a guaranteed way to give a touch of stylish casualness to your look. So when summer is done and fall is in the air, this outfit is likely to become your uniform. Think it's hard for mature men to perfect modern off-duty outfits? This pairing is a practical demonstration of otherwise.
