I am a true size 8.5 in sneakers, 9 in boots, but 9.5 in La Sportiva's trail running shoes. I decide to buy a 9 and 9.5 so I can try them on at home. I ended up keeping the 9. I hiked 9 miles in them the first time I wore them. They felt amazing, no blisters, no need to break them in, no foot fatigue. I can't get over how cute and lightweight these boots are compared to others on the market. I am so happy with my purchase! I love the feel of these and the look. I decided to return after I read some reviews, thinking I need the La Sportiva Nucleo for more support with a 45 pound backpack. I wish I could afford both!
