I have used this shoe for 2 weeks now and right from the start i knew my barefoot shoe patience had finally rewarded me. I have used barefoot/ minimalist shoes for quite some time now and have gained insight from learning more about foot mechanics, running form, and the importance of a wide enough toe box. My first impression was that the shoe is so light and form fitting that it feels like its a part of your body. I took them on a trail run and its responsive midsole/outsole made it feel like i had a super strong and elastic-like fascia (look up Dr Mark Cucuzella's book if you wanna learn more about this) since i felt so bouncy. This protective mid/outsole is thick enough to protect you on technical terrain but just enough so that you can feel the objects, rocks, holes, and uneven terrain you are landing on. The grip performed stellar since i have not slipped or fallen on dirt, rocky, or muddy terrain even when running in the midst of rain. They also perform great on pavement so I was surprised to learn that they are creating another model specifically for road running (sign me up for this one and their next tennis court shoe). The materials this shoe is made of seem very durable but very light at the same time. This is probably the lightest running shoe i have ever worn.
Now for the foot shape of the shoe: I have mountain shaped feet, which means that many of my toes are of similar length. This means that the tapered lateral side of the toebox can make contact with my 4th and pinky toes. My longest foot measures 26.5cm and Notace recommends adding 1.25 cm to your foot length to choose the right size and i landed on the size 10. This size 10 made too much contact with my 4th and pinky toes so i 1/2 sized up. Notace CS was on point, i received my new size 10.5 pair a couple of days later and my toes were able to splay freely. Since I sized up, I added an insole in order to fill in the shoe a bit better. My feet are low- to medium volume and this shoe seem to have a lot of volume. This means I also had to tighten the shoe a bit more so i replaced the shoelaces for shorter ones to prevent tripping on them.
Overall, as you can read in this review, i am beyond thrilled with this shoe. I ran my first 5k trail race today and they were so fun and nimble to race in. If Notace asked me if there is any room for improvement i would add 2 things: 1) make the last of the shoe less tapered so they can better fit pizza shaped feet, and mountain shaped feet (although this can be remedied by size 1/2 size up). 2) Separate the eyelets a bit more from across each other, so that cinching the shoelace can resolve any fit issue ppl with low-volume feet may have.
