Possibly the worst shoe I have ever bought.  That is not a hyperbole.  Take a look at the photos.  In less than 5 miles, I repeat, less than 5 miles, these shoes were destroyed.  Literally falling apart.  This was not even a trail run.  This was a hike on a very laid back trail.  The lugs were tearing and ripping off.  Take a look at the pics.  One of the red lugs actually ripped off.  1/4 of all the lugs had torn, in less than 5 miles.<br /><br />Alright, so there is zero durability in these shoes.  I mean, if you can't even get a sole right, I don't expect you to get the rest of the shoe right, and they didn't.  The shoe narrows and is not as wide as I had hoped for.  I had to wear a size .5 larger than normal, to allow my small toes room.  This is because the shoe narrows to a point, as opposed to slowly tapering towards the big toes.  Merrell has this down, Vivo does not.  The shoes were slopply, lacked grip and durability.  I mean, I just can't say enough bad things about this shoes.  The lacing system is just dumb.  Just put normal laces on your shoe.  They don't stay tight, and they don't allow you to customize the fit, as much as normal laces.<br /><br />Trail Condition: Rocky<br />User weight: 175<br /><br />CONS:<br />-Zero durability - lugs tore off and separated in less than 5 miles of walking - side of shoe tore<br />-Fit is all wrong - front of shoe comes to a sharp point which means you have to size up to fit your small toes in.  Shoe is narrow in comparison to many other barefoot brands.<br />-Lack of grip - you would think it would be superb and that is why the sole is so mushy, but no, the sole is mushy and not grippy<br />-Ugly as can be<br />-Too much cush, and still does not protect from rocks<br /><br />I'm done, I'm trying to think of the best way to describe how awful this shoe is.  Just don't buy it.  Honestly, I'll never buy another vivo and will steer others away.<br /><br />For reference, my favorite barefoot trail shoe to date, is the Merrell Trail Glove VERSION 1.
