The Good:  The Keen Concord Slip-ons were shipped fast!  They are nice looking casual leather street shoes  They are good to wear with jeans or casual work clothing year round.  The footbed fits true to my usual 8.5M shoe size.  There is no way I would increase the size I bought, because then the back of the shoes would slip off my heels while walking.  The Bad:  I understand why some people might not keep these shoes.  They are a bear to get on.  I had to use a long shoe horn and really push my feet into the shoes.  Right out of the box, the leather uppers are extremely tight across my instep and the insoles of the shoes are harder than I expected them to be.  Final Note:  I am keeping these shoes because they so look nice, are made well and  were value priced when I purchased them.  I think they will break in and loosen up to conform to my feet and work out just fine for me.  Eventually, I hope to be able to wear regular socks with them to add extra cushion and warmth in cold weather.
