Good shoe

Very Cushiony but would like a bigger shoe. I normally wear a 14. They are tight but in the future make a 14

Very comfortable and stable shoe

Love this shoe very comfortable, stable and reactive! the only problem in my case is that my normal shoe number is 14 US and the biggest size available is 13 US so it’s a little little bit too short for me. Please make sure you produce also bigger sizes and activate again the shipping to Europe!

Yes!!

I bought the shoes for our son who just ran the Cocodona 250 and should have bought em sooner!! I feel pretty certain these have been a good investment for his running endeavors, thank you!
