I have just had these boots for a couple days now and know there is always a break in period with most shoes and especially boots.  I have numerous pairs of boots.  I ordered the 9EE because I do have a pretty wide foot.  The length for me is right on.  But for a EE which usually gives me enough side space they're pretty snug.  I hope they'll stretch out a bit.  I got these primarily for work also.  I do like the tread on the sole, they seem pretty aggressive, so we'll see how they do on slippery or wet terrain.  Hopefully they'll last for years!
