These shoes do run a bit narrow. I'm between a 9.5 and 10. I opted for the 9.5 b/c my foot was sliding too much in the larger size, but the 9.5 is slightly narrow for me. I probably couldn't walk for hours but if you are a true size 9.5 I think they would be great. Keeping them, just not using them for the long haul.I love the way these look and feel. They are comfortable for walking all day! I have traveled with them and walked a ton in them. I liked them so much, I got them in 2 colors!!!The sandal fit length wise but the strap between the toes was too far down and really hurt! The next size up would be too large for me. I wear between a 9 or a 10 and the 9.5 length was the right length for me.Love this shoe-have 2 back up pairs!Love this shoe!Have worn them twice and they broke.
