Great comfortable shoes. CAVEAT EMPTOR the soles wear poorly. I unfortunately have had these soles fail a year later on 3 or 4 pair of Ecco's. You can't get this resoled with the polyurethane soles, for a $100 you get a Vibram sole complete different dynamic to the polyurethane sole.

Query one of the following and you will see my Ecco's are not alone.
Ecco Shoes - Shoe soles disintegrating
Ecco Shoes - Terrible experience
Ecco Shoes - shoes (sole) falling apart
Ecco Shoes - great uppers rotting soles
Ecco Shoes - soles disentergrating
Ecco Shoes - SOLES DESINTEGRATE - ON BRAND NEW SHOES
Ecco Shoes - Cracks in Soles
Ecco Shoes - Disintegrating Soles
Ecco Shoes - Soles falling apart
Ecco Shoes - Fall Apart

Ecco is totally unresponsive to this problem they are aware of.

Good fit, extremely comfortable, and uppers are durable, the soles are horrible deteriorating prematurely and creates mess. So if you are willing to pay the price for a sole which will last a year they are great otherwise they are a mistake. Good luck.

There is a Youtube video which unfortunately represents the sole problem:  [...]
or if the hyperlink doesn't work the title is 'Ecco Track II - Boots Sole Disintegration'.

I have purchased other Ecco shoes with different sole compositions and have had better success.  During additional research while Ecco denies the problem they stated they have re-compounded the soles composition.  GOOD LUCK IF THE SOLES LAST YOU HAVE GREAT SHOES, IF NOT JOIN OUR 'SAD SOUL SOLE CLUB'.
