Ordered my normal size, it was good in length but too narrow and combined with thick hard upper leather compared to my Ecco or Sketchers slip-ons did not feel comfortable.  The Lunarlon sole was nice however and gave 1/4 inch give or take.  Also not a fan of the slick leather unremovable  insole.  Will try another Lunarlon model and bigger size at a local outlet with lower prices.  Will also bring a Powerstep insole with me and see if that helps.
