"In comparison to the X4s, these are an immediate upgrade and worth the price difference from the wider toe box alone." — B. W.

Reviews
Raw Achilles
"I keep hoping that these will break in but I’ve gone through a lot of bandages / tape trying to mitigate a rubbed raw Achilles on one side only (left). Fit is also a bit tricky, they’re either sliding around on my feet or tied tight make my foot almost numb. I’ve tried a couple sizes, it’s not a size issue, it’s a fit issue."
— Michael K. (2/5)
Not my favorite nano
"I don't know why they have to change the features so frequently. This shoe is wide. The sides are low around the ankle and high on the heel. It rubbed the back of my ankle raw. The sizing is true to size it's just all the little things make it not good. These got returned and I bought the X4"
— Sluchick (3/5)
Small sizing
"I upgraded from my nano x3 to this one Breakaway Green/Washed Black/Grey 3, size 10 however the sizing is too small , idk if it’s because it’s a color not popular so maybe they shipped it from Vietnam or idk why this color model they made it on small sizing , but my size 10 feels like a size 9 , and what’s even worse it came with some defects , the upgrade was def not worth it , can’t even wear this shoes"

Great stability for workouts that combine runs with strength training
"Perfect! Great fit, Much better stability than my running shoes - perfect for workouts that combine running with strength training. I'll still use the running shoes for long runs. . . Super happy with my decision to buy these."
— Scott A. (5/5)
Solid training shoe
"A little wide for my foot but that's not uncommon as I have a very narrow foot. Feels supportive during lifts but also comfortable for running and jumping. Sizing was a little tricky but exchanges were easy and I was able to get the size I needed."
— Elisa L. (5/5)
Good shoe
"Works well for the HIIT classes I take. Only knock is that the traction is just fair -- it's not great on a slippery (sweaty) floor."
— Charles S. (4/5)
F45 All Around Gym Shoe
"Great fitting, solid surface grabbing sole, good for F45 HIIT style combo workouts of cardio, plyo, and lifting. Nice look to add, and quality laces that are important to keep ya set and locked in for your workout. Personally I could use a bit more arch, but that’s typical of any shoe for me. I’m about a month into these so far."
— Steve Y. (5/5)
Nice

— Francois D. (4/5)
Size down by a half size
"I love the shoes 10/10 but they are a half size too big"
— Robert J. (4/5)
Big Fan
"Slick looking shoe. Comfortable on walks."
— Jason R. (5/5)
