While they are not the most uncomfortable pair of sneakers I've ever owned, they are the most uncomfortable pair of Rykas.  I swear by Ryka's, they fit my feet properly and have superior comfort which is why I feel comfortable online ordering them.  It is the only sneaker for me that really doesn't require trying on which is why the Trail Exodus 2 surprised me in a bad way.  I have fussy feet, arch problems etc.  When I slipped the Trail Exodus 2's on (I got the pink taffy, citrus color), they were alright.  I walked in the house, they were still ok, not the most comfortable but not bad either.  Then I walked my dog.....on pavement, my feet suffered.  In particular, the heel felt over supported...maybe the word is just plain hard.  I was keenly aware that I had a left heel and it bothered me almost the whole walk.  I'm used to not knowing I have feet in Ryka sneakers.  There was no pillow comfort in these, the inside was dense and unforgiving.  I can't imagine the blisters I'll get for long term use.  I'm going to try to return them but I think I'm probably stuck.  Either way, I'm not wreaking my feet with these sneakers.  I'll be buying another pair of Ryka's for sure but I guess I have to go back to trying them on first.
Follow up- Amazon is the best!  They let me return the sneakers.  I have purchased a new pair of sneakers and because I was leaving for WDW in 2 days, I didn't have the leisure to run to a store that sold Rykas.  My current sneakers are Asics and they are comfortable enough, though I my blisters had blisters after 4 days of walking in WDW.  I will wear them out in 6 mos. and return to my beloved Rykas.
