Is the 928v3 good for overpronation?

Yes. It is one of New Balance's motion-control walking shoes, with a ROLLBAR post and a firm heel counter that limit inward roll. It suits flat feet and walkers whose feet turn in.

How does it compare with the 928v2?

The v3 keeps the same ROLLBAR and ABZORB setup but updates the upper and lining. Owners of the v2 generally find the fit and support similar, so there is little reason to switch unless the old pair is worn out.

Does it run true to size?

Most buyers say it fits true to length, and the multiple widths let you match your foot. If you wear thick socks or use a bulky orthotic, consider going up half a size.

Can I put my own insoles in it?

Yes. The PU foam footbed is removable, so a custom orthotic or a different insole drops straight in. The firm base under it still gives the stability.

Is it good for standing all day?

It is built for that. The firm support and ABZORB cushioning suit long shifts on hard floors, though the weight is noticeable if you are on your feet moving constantly.
