This has happened all my 270's and 330's,usually after the first couple of races (though not to the same extent on my flyrocs), the orthotics I have do not seem to stop new shoes rolling but seem to offset a little the ankle and back problems I get if I continue using them when rolled. 270's seem to be a bit more resilient in this department and feel like the better shoe to my feet than the 330's and I wear them for longer races. Pleased its not just me though I don't think that helps overall.
