I really like Keen footwear.  I ordered them for the steel toe protection and the ease of use.  I have other keen slip-on boots and love them. These however are very tough to get on and off.  They made the heel support very rigid.  That would be okay on a lace up but on a slip-on I can barely get them on.  The pull tab on the back is made for a child's finger.  Basically useless for a man sized finger.
