I have wanted some La Sportiva trail running shoes for a while now but had been hesitant about buying online because I heard they run small. I went to the La Sportiva site to read reviews and information about sizing and sized up as recommended. I normally wear a women's size 9 with an average to medium fit. I ordered the 9/10 and they fit perfectly!I just got them, and even though it's raining, I decided to take a trail run through my woods. The terrain is definitely technical with gravel, rocks, roots, hills, wet leaves and pine needles, mud, puddles, and some wet grass. I also had my very hyper Jack Russell Terrier running with me on a lead, and she's sometimes all over the place.The shoes performed brilliantly! They're lightweight and hug my feet nicely. Though they're below my ankles, they give great support. I felt like I was gliding over the terrain. Some of the hills had wet pine needles and I could run straight down with no toe crunch or side winding my way down.I ran through some thick mud and didn't sink too bad and my feet stayed dry. The only thing that slowed me down was I got out of breath a couple times or stopped when the doggo ran out in front of me.They're so comfortable I haven't taken them off yet. I wore slightly thick Smartwool socks and my feet didn't sweat or feel cramped.I only just got them and this is my first run so if anything changes I'll share an update. 5+ stars!!
