Five Ten - Women's Niad Lace - Climbing shoes

I've order these climbing shoes in size EU 39 1/3, as my other climbing shoes (La Sportiva) are in sizing EU 39. And my normal shoe size is EU 40.
I have order this pair as I remember that 5.10 Anasazi used to be n. 1 climbing shoes in the US few years back.

But the shoes are at least 2 sizes smaller than they are claiming them to be! The sizing chart is absolutely off. The Eu 39 1/3 are in real life probably EU 37. I could not fit my feet in them at all. The shoes are also very narrow fit, so keep this in mind.

I am very unsatisfied as I had to return them and to pay the shipping fee due to misleading information of the manufacturer.

So please be cautious and try these climbing shoes in store only because otherwise they will not fit you.

I was initially drawn to these Five Ten climbing shoes because they look great, but unfortunately, that’s where the positives end.
Sizing is a serious issue. I ordered half a size up from my usual sneaker size and a full size up compared to what I normally wear in other climbing brands like La Sportiva, after reading that they run small. Even so, the pair I received feels at least two full sizes too small. This goes beyond a typical tight performance fit and points to misleading sizing information.
To make matters worse, returning them costs an additional €10, even though the sizing discrepancy is clearly not the customer’s fault. Overall, a very disappointing experience.

I wear a 42 size casual shoe and usually a 41 in climbing shoes (La Sportive reference!) .... I have the 43 1/3 in the NIAD. After I bought two pairs that were too small, this large size fits like a glove. The shoes are now an absolute dream for edging, slab climbing, and Multipitches.

I have tightened feet and it fits excellent, especially after few times of wearing

Fits like a glove. It does run WAY smaller then my LaSportiva. As a comparison, my Solution is 3.5UK, this one I am wearing 5UK (on purpose as I am recovering from an injury, I wanted a bit bigger, still, the 4 could not even fit in).
It is impressively comfortable. I had an anazasi pro and hated, as it hurtme until its end of life... and after resoling it o_O
Super good grip, non aggressive, good toe and hook. I got it to be my confi multi and bouldering shoes
