The La Sportiva Boulder X approach shoe is a comfortable, supportive shoe with sticky rubber on the sole to allow for easy-going on steeper and rockier terrain. An excellent all-around performer, this are a touch heavier than others in the genre, but provide better support and durability in turn. 

They are used, but not much (less than 5 days / 20mi). I got them for my wife but they ended up being a 1/2 size too big so they lived in the back of the closet for a few years before I decided to sell them. 

Happy to provide more intel or photos, just reach out. Located in the Front Range, a bit north of Denver.
