Like all my other Ecco footwear, the Track5 is very comfortable right out of the box.  I'm sure these hold true to my other Ecco boots: waterproof, warm, durable, etc.

However, I have an issue with these boots.  Maybe Ecco changed the material of the sole or something, but these boots are EXTREMELY slippery when they comes in contact with grease!!

I work in a field where I am in contact with grease everyday....slip resistant is very important.

I'm currently wearing a pair of Track 4 that's 3 years old and have no issues with grease.  When I wear these new Track5 to work, I feel like I'm going ice skating!

I'll give an update once winter hits.  Hopefully these will be able to handle ice/snow as well as my old Track4s.

UPDATE 1/23/11: These boots are COMPLETELY HORRIBLE in wet conditions.  Things are ok, as long as the surface is concrete.  But once you walk inside a shopping mall from the rain, brace yourself.  You're going to feel like you're walking on ice.  For some reason, the soles on these boots are horrible when they get in contact with a slippery surface (like tile floors in a shopping mall).

I have no idea why other users never noticed this.  Maybe it's just my pair?  Maybe it's the latex sole?
