After wearing my Adidas 2G slides for 4.5 years, I decided it was time for a replacement.  While I was generally happy with those slides, there was on irritating design flaw -- inadequate Velcro closure strength.  This weakness appears to have been rectified with the latest generation, the Superstar 3G.  When the previous shoes would occasionally tear open, it would lead to a rapid slip of the foot and painful kick into a wall or desk. It is nice to have this problem go away.

Both generations of slides have been used entirely indoors and until recently, always on carpeting. It is surprising that the 2G slide soles exhibited significant wear on the soles within a few years of use.  While only time will tell how durable the new version is, the soles are equally as soft.  Oddly, and somewhat counterintuitive, both generations exhibit poor traction on new laminate flooring.  The problem is dramatically worse with the slightest amount of dust.  The problem partially lies with the floor material but the slipping isn't nearly as bad with traditional cross trainers or even dress shoes.

Overall, the Adidas 3G slides are well-made and comfortable.  The Velcro flap accommodates wide feet and remains firmly attached, which is a welcome improvement.

Pros
Improved Velcro closure strength (vs. 2G)
Comfortable padding
Solid overall construction

Cons
Poor traction on laminate flooring
