I have gone through a few pairs of the New Balance 655s now. Ever since I switched to a new pair of shoes a few weeks ago, I get some minor pain in my right Achilles heel after I play. The next day I don't feel anything. I tried adding some shoe inserts but that did not help. I'm wondering if I should simply switch shoes or try some insert like Superfeet Orange (which CharlieFedererer recommends). Any suggestions would be welcome.
