I normally wear a size 7.5 or 8 narrow, so after reading some of the other reviews I decided to order the size 7 and glad I did.  With a cushy insert and heavy socks, they fit acceptably with just a little movement side to side. However, I think a size smaller would not take care of that, but only make the ends hit my toes. The calf area is perfect for me to fold in my outdoor work/garden pants; not too wide and not too tight.  Perfect height, weight and hunter green color. Will suit my needs perfectly. For a slide on boot, not sure you will find anything better.

Update:  After wearing these around the farm, up and down hills and around the pond where my feet were in and out of mud and water...I really like these boots. I do wish they fit tighter around my heels, the only reason I can't give them 5 stars.

Second update: OK, so I've had these boots for two years and the lining is coming off the inside of the rubber near the tops of both boots; very annoying when putting them on. Both buckles have dry rotted and come off, but were not functional anyway. I still like them and use them for muddy work, and for the price, I might still buy them again.
