are keen sandals true to size
View. My first pair of Keen sandals were a size 8.5 and it was a couple years before I saw signs of wear and tear. This pair I purchased was size 9.5 (comfortable with a pair of thick wool socks) so in the last 6 years the sizing has changed. am a true size 8 but I usually have to go up a half size in Keen because they run a little bit smaller than usual except for in the Newport H2's I wear a size 8 and they fit perfectly. These shoes are way comfortable and you could walk in them for hours.
