Just picked up a new pair of Bates boots this weekend and I love them.They're comfortable,waterproof,and they're side zip for easy removal.I noticed as I put them on for work tonight that I have to untie them to slide my foot in.I've never owned side zip boots before so I was curious if this is normal.If not,what do I do?Tie them loose and lose ankle support?Untie them when I take them off?Please advise.
