Customer Reviews Reebok Nano X3

Really loved the fit and comfort of this shoe. It was great for HIIT and pickleball as well as lifting, but it just didn't last. I rotate shoes so at most wore this twice a week since purchasing 4 months ago, and the sole has already have given way. The back of it makes a large clicking sound where it has broken. The shoe doesn't LOOK like anything is wrong on the sole, but it is so loud that people have asked me if it's my knee making that noise or what. Can NOT wear these shoes after 4 months because of the horrible sound with the broken sole, and not sure that I should...would they really be supportive if they are broken? Buy something else.

They are not as comfortable or flexible as my other Nanos. They are pretty stiff.

Not as supportive as the walking shoes at all. Decent arch and heel support. Zero support for front of foot. Wanted to use for exercise but my feet hurt with casual use. Top of shoe creases and hurts

Shoes feel like they're bigger than they should be. I ordered my size but feel I could've gone 1/2 number down.

Very dissapointed, I should have taken a size 9. But the sizing chart said 10.2 (25.9 cm) is 10 US. I got my Size 10 US: Eur 41: 27 cm. Its 1 cm to big. Im very disdapointed.

Can see glue lines in the seams against the solid color. Shoe seems to run a bit small. Can't feel arch support, so hopefully foot will conform over time to the shoe. Lightweight feel.

These shoes look nice and I feel like they're decently comfortable, but they rub on my ankle a bit and sometimes they feel too roomy. Like they're too big. But they're wide enough for my feet. So idk.

I leave loved every pair of Nano's I have had except for these. The only thing they are really good for is lifting. Running in them feels like you are wearing cement shoes.

I wasn't able to actually crossfit in these shoes because the fit was off for me. I am a true size 6, and I have a narrow foot. These shoes were had over an inch of room between my toe and the top. The toe box is pretty wide as well. My foot had too much room.

I loved the nano X2s I don't even need to break them in because they have a comfortable wide toe box. Which is what most shoes should have. Due to sneaker manufacturers putting style over comfort most people have messed up feet due to narrow unnatural toe boxes. I hope Reebox make a wider toe box for the next generation or I will have to find a new brand sadly. I will say the style of the X3 are amazing.

I have narrow feet and found I had to size a 1/2 down. The first pair I got, the insole was not glued properly and caused a huge blister on my inner foot when I ran in them. Second pair: Good for hiit, not as great for running. Shoe sole is not very bouncy/feels hard.

Runs big, I normally wear a 7.5-8 in athletic shoes and ended up with a size 7 in these. The toe box is nice and wide which is great. And the shoe feels quite stable, almost too stable. The sole has very little give to it which is quite uncomfortable if you're walking, running or doing anything other than static lifting. The heel/opening of the shoe is also quite loose. I used a heel lock lacing method to secure the shoe to my foot. It's a nice looking shoe, but unfortunately, not very comfortable to wear.

When buying any Nanos, be prepared to double knot each and every time. Otherwise, you'll find yourself getting caught doing metcon, double unders, running, what have you.

Fit and aesthetic are good. I do wish it had more arch support and feet cushion.

The first time I wore it, my feet were sore and I thought it needed to be broken in, so I wore it almost everyday to speed it up. It still hurts. I specifically bought these shoes for conferences where there's a lot of walking involved. I walked around Kyoto and my feet were screaming. The X1 and the Nano 8 did not give me this problem. The Nano 8 was my first Reebok buy. I won't buy Reebok again. How can shoes from the same make and model differ so much in performance? Second, the plastic design on the inner midfoot rubbed badly, initially.

I was really excited to finally change out my Reebok CrossFit Grace shoes for the new Nano X3's however it was definitely a miss for me. They didn't fit my removable insoles without feeling like my heel was going to come out of the shoe when running or rowing (especially). (And yes, I did remove the removable insoles that they came with before trying my own inserts.) Also the Nanos felt really chunky and big overall (which seems ironic with the insole issue) such that they were terrible for double unders and feeling coordinated generally. Really disappointed, as I splurged for one of the pricier color ways too. Switched to another brand's very popular CrossFit shoe now and much happier with the fit and ability to fit my insoles in.

Toe bed is too wide so the top buckles when tightening the strings. X1 didn't do this. I wear size 8 and dropping to 7 1/2 would put my toes to close to the end.

I bought these for a gym workout class (HIIT, lifting, cardio, etc) and they usually fit great in the toebox. They are now making them so narrow. They run really tight in the toebox.

Either the shoe runs extremely large or mine was sized wrong. It clearly was not a 6.5. I gave them to a niece who liked them. I could not wear them. They were way too big.

I do Crossfit 5 days a week and X2s were my go-to shoes. I bought these and loved them the first time I wore them, then I started having knee pain. They are overly stabilizing and cause knee pain.

They are very uncomfortable!!! They arent good to training! And too big
