Here is another example of Buyer Beware. CF came in today with a new pair of Asics Gel Evolution 4. She had worn them for an initial 2 mile run and started to experience left forefoot pain. This was discouraging especially since her last shoes caused arch pain, which I’ve also blogged about http://drshoe.wordpress.com/2008/10/29/shoe-review-mizuno-wave-rider-11/
Upon close inspection, I discovered that the grey EVA midsole were of different lengths in the right versus the left shoe.
In this case the amount of EVA in the left shoe extends less forward than the EVA in the right shoe. This results in vastly different flex points in the forefoot as the grey EVA is much firmer than the white EVA as this image shows.
As most of you know if you’ve read my blog, I am a huge fan of many Asics shoes, so I’m not being dispariging to their brand. This is simply a manufacturing error and one more instance where buyer needs to beware.
