(+) My ideal pair for air travel "long distances" ('more than 6:00) and other land travel with high temperature differences (Asia, Middle East, Paris in summer ;-)) = flexibility and comfort
(+) Effectively padding, and terribly efficient lacing system (the wife shoe foot)
(+) = Vibram sole non-slip stone / wet rock (useful when it rains)
(+) Cushioning in the heel for comfortable walking, without falling into too "soft" AIR models from XXXX
(+) For me, size 43.5 (and not 43 or 44): it is little but it makes ALL the difference for comfort
(') A little expensive!
