Kanadia 4TR is nothing like 2 TR. I love my 2 TR shoes - but I tried 4 TR last weekend, and I was very disappointed. WHile they are as light as 2TR, they are much more rigid, especially the top part that kept poking my foot. I didn't like them at all.... I opted to get NIke Climawarm Blast instead. They felt much better and more flexible.

Mind you, I do not run or use trails or do anything sporty at all, I only walk and use these sneakers as an everyday sneaker. My 2 TR served for me exactly 3 years to date and now the mesh is starting to tear in places.

I love Adidas shoes in general and have only worn Adidas in the last 20 years.
