I love these shoes so much, I have two pairs in different colors, and I LOVE LOVE LOVE them both. I am a big NB fan, their shoes always fit my feet better than any other brand. I originally bought a pair just to wear around for daily use/errands and such. I really loved the style and color. When I first tried them on, I felt like the fit about a 1/2 size big, however I think that was just due to the roomy toe of the shoe. I almost always wear a 7.5 no matter what the style/designer. I bought my first pair in a size 7 and they fit great for walking around, running errands etc...

When I ran in them, they felt great! However, I knew right away I needed a 1/2 size larger if I was going to run in them all the time.

I ordered a 7.5 for my running shoes, and I love them. There's so much wiggle room in the toes width-wise that I never have achy toes after a run. I view these as my "step up" from minimal/barefoot shoes because while there's not a lot of cushion, there's still some.

I would suggest ordering true to size if you're using them for errands and daily wear, but if you intend to use these as running shoes, I'd go at least 1/2 size up, maybe a full size if you have long toes :)

**UPDATE** I have been running in these shoes for about 6 months now, and as one reviewer also stated the mesh is starting to come apart, right where the foot bends. However, it is just the top layer of mesh that has "worn" and the shoe is still very much usable, there is no hole all the way though... and looking at it, I don't think there will be. This has happened on both of the shoes I own, my running shoes are a bit worse than the other pair. This would NOT deter me from buying this shoe again.

Before these shoes, I tried a number of different shoes like Brooks Pure Connect, and Reebok Real Flex and a few others, and I feel these NB are light enough for me to carry on a 5-6 mile run easily without any pain in my calves, shins or ankles. I'm still very happy with these, and would for sure buy them again.
