Size up

Typically a size 10 in all shoes. My toes hit the front of these 10s. Going to order a 10.5 and see. Love the shoe otherwise just need to likely size up.

Built for durable and supportive comfort, the MC Trainer 4 gets updated with softer foam and a lower base for a more powerful feel. A lightweight and breathable mesh upper pairs with lockdown support and flexible outsole for all-around comfort through every movement.

Great for Hybrid Training

I am a metcon 9 girl through and through for my weightlifting classes but recently I have tried to incorporate more short distance running and was on the hunt for new shoes that gave me all the support of my metcon 9s but felt softer on my foot. I decided to give these a try and I absolutely love them! So soft and comfortable, has that strong wide base I need for lifting but the flexibility to run and they feel good on my feet. Highly recommend if you are someone who takes hybrid HIIT classes or does any type of hybrid training.
Runs super small

I’m usually a size 8, but Nike is the only brand where I always have to size up to an 8.5. All of my Nike sneakers are size 8.5 and normally fit me perfectly. Unfortunately, this black pair runs VERY small. I ordered my usual Nike size 8.5, but my toes hit the front of the shoes and there is absolutely no extra space. They feel more like a size 8. I’m wondering if the sizing issue might be why this style is on sale. I do like the shoes, though, so I’m going to give them another try and order a size 9. Hopefully that works! Definitely consider sizing up in this style.
