I am on my fifth pair of these shoes and regret that I have to reduce my rating by three stars. They have completely cheapened the shoe and it is now a really crappy shoe.  One of my favorite things about the original was the strength of the back and sides of the shoe, providing good lateral support and standing up to abuse.  The current shoe is nothing like that.  A tiny push and the back of the shoe collapses like a house of cards.  Every time I put on the shoes I have to dig the back of the shoe from under my heel.  There is no lateral support to speak of.  It may look like the old shoe but it is a cheap knockoff of the old shoe.  I may be stuck buying another pair when these wear out  -- I wear size 12 6E and use orthotics so I don't have that many choices when it comes to shoes but after what they've done to this shoe, I hate to give this company any more money.

Original Review: I really like these shoes.  First they are really comfortable.  The standard liners are nicely supportive but they come out easily and leave plenty of room for orthotics.  One of my favorite things, though, is the lateral support.  With most slip-ons the sides are somewhat soft to make it easy to get them on and off but many are so loose they feel more like slippers.  These are somewhat different.  The opening is flexible, yet rather rigid and the sides are quite sturdy -- slipping my foot into the shoe takes a slightly stronger push than the average slip-on, but it is still quite easy and once they are on my feet, they feel nice and snug and when I stand my feet feel like they are being held in position.  I like that feeling.  Also, the back feels quite strong -- I suspect one could pretty much carelessly force one's feet into these shoes day-in and day-out without a shoehorn without ever having to worry about breaking down the back of the shoe.  Besides I think they look really nice and while it never occurred to me that suede might be washable, they claim that one can wash them.  How cool is that?  Very nice shoe.

I recently bought my third pair of these shoes so I thought I would update my review.  I still love the shoes (I'm on my third pair) though, honestly, I am a little disappointed in their longevity.  Part of that problem is me, I suspect, as most shoes I buy wear out faster than I would expect.  I thought these would last however as they seemed very sturdy and well made.  Well, I think they are very sturdy and well made -- certainly, nothing was truly worn out -- the soles were in great shape and the shoe still looked good but that snug support I wrote about eventually went away and as I have some stability problems the shifting of the shoe on my foot presented problems.

With my latest pair, however, there is another problem which was not present in the first two pairs.  When I tried replacing the standard insole with my custom orthotics, the extra thickness of the orthotics pushed my instep hard into the front of the foot-opening on the shoe which eventually resulted in a lot of pain in my instep.  I don't know if this is an indication that dimensions vary from pair to pair somewhat more than I would think is reasonable, or if the design may have changed a little from the last pair I bought.  At any rate, it is still a great shoe, and I will probably buy another pair when it is time to retire these.
