Difference between Teva Psyclone 2 and Psyclone 5. See pictures! I was a huge fan of Psyclone 2 (purchased 2014), but not Psyclone 5 (purchased 2015). Psyclone 5 has a much narrower angle to the toe part of the shoe, meaning my son is already outgrowing them because of his big toe (see picture).....as opposed to his whole foot outgrowing like a good angled shoe. The pictures also show: --Psyclone 2 was much wider, which I have found better for toddler feet. --Psyclone 2 had a much better arch support. --Psyclone 2- UPDATE: obviously higher quality material, showing almost NO signs of wear on the sole after 2 summers of use!!! **added last picture If you are wanting the same high-quality Teva shoe you have seen in the past, you won't find it in the Psyclone 5. We probably won't buy this brand again, unfortunately.
