Kent,
I'm sorry to hear that you are having issues with your Wave Creation and I agree with you that they shouldn't be 'giving up the ghost' after 200-250 miles. Without being able to see the shoes in question to pass a more informed response, all I can say at the moment is that the major difference between the Kayano and the Wave Creation is that the Creation is a neutral shoe and the Kayano is a stability shoe,I would therefore expect slightly greater midsole durability from a stability shoe due to the firmer midsole density. Have you had the chance to have your gait analyzed to ensure the Wave Creation is the correct shoe for you ?
With regard to your returned Wave Creations I can only apologise for the fact that you have not had a response, and can fully understand that you are not impressed. I will personally investigate this with our customer services department and ensure a response is sent back to you immediately.
I am sorry that we have lost you as a customer for the time being, hopefully you will one day try out our products again.
Best Regards
Simon Ash
European Product Development Manager
