After researching and hesitating about spending this much on a pair of shoes, I am so glad I bought these. I have been  an Asics fan for 10 years, and these top the list.
They are pricey, but to me ,these offer a superior ride. THey fit well in the ankle and have nice room in the toe box, and I think are true to size. I also bought Newtons minimalists at the same time  , thinking I may need to  try to change my stride.  After trying these Asics Kinsei's  and videoing my gait , I find they  do not hinder my natural  midsole strike even though they have fantastic cushion in the heel.
