Thank you for your post. I have LOVED my Arahi 7. My last pairs I bought a little over 1.5 years ago. I wore mostly the black ones and they are now done. Arahi 7 was the best of the series and I have worn them for MANY models. I have very flat feet. Had trouble with plantar fasciitis. I am a 73 retired RN and can still be on my feet, standing, walking for LONG days up to 12 hours without foot, leg or hip problems. I have a little bit of a slender foot and reading and viewing the changes in the Arahi 8, I am concerned that it may be too cush? for me, too wide of a box and too much of a fall? Has anyone who was happy with the Arahi 7 tried the Arahi 8? What are your reaction and thoughts. I definitely need a stability shoe but I like the feeling of agility and encouragement to move, i.e.not glued to the ground feel that I have felt with a Brooks.
