Ran about half a size small for me.

Full disclosure, I ended up returning but may repurchase and only tried on around the house. I typically wear a 9.5EE or 10D in Adidas (Ultraboost 19) and New Balance (990v5s and Hierro v5). Nike runners are typically too narrow for me in 10. If it helps in Chucks 9.5 and 70s 9. For the Mont Blanc 10.5 was a good fit in length and maybe a touch narrower than what I would have expected, bearing in mind this isn’t their wider fit. Loved the Boa system but found when I tried the 10, bearing in mind I returned though, I could feel the back of the Boa dial through the fabric/padding on the interior. Like the look and Boa system but recommend trying in person or sizing up possibly if you have wider feet. Can’t speak to long term durability but the upper seems really well made. The cushioning is similar to NB FreshFoam in the Hierro, but maybe a touch more stable.
