I love this shoe!  I walk my dogs at least 1 hour per day on different types of surfaces, including streets, sidewalks, hiking trails, forest, and grassland.  I was able to wear these right out of the box the first time, with no hot spots or blisters.  They do it all, and the foot bed feels very supportive, which I don't find in most shoes.  I have had to add additional sole inserts to most of the athletic shoes I have purchased in recent years, but not these!  My measured shoe size is 8.5 and the size 9 is plenty roomy with a padded athletic sock.  I will definitely by Keen shoes again!
