If you are size 40.5 in Asics running shoes...

Could you tell me what size you wear in Nike please? I'd really appreciate it as I don't have time for returns atm (does anyone?). Asics seem to run small for me as I'm not 40.5 in any other brand, but the reviews for Nike say they run large so I don't know where that would leave me. Thanks.

Not quite the same, but I’m a size 5 (38) in Nike and most other footwear, but a size 6 (40) in ASICS.

I would consider going one size up.

I think you mean a size down, don't you? Because I have the Asics size (40.5) and need to find the Nike size that fits someone who wears Asics 40.5, and general reviews and what you posted also indicates Nike would be smaller.
