Argentina’s men’s size

[UK Man]

My wife recently bought me a pair of CAT leisure shoes here....they are a perfect fit.
In the UK I'm a size 10 however the CAT's she bought me has printed on them. UK 9.5 USA 10.5 EUR 43.5 and for here are classed as M.
Much of course will depend on the brand and shoe style. I'd forget it to be honest, not only due to the game of chance regarding delivery cost and time.
Send him the money as he might be able to get the same shoe here.

If you'd like to order your friend some nikes I'd recommend buying from their official shop on Mercadolibre and sending them to their home - they'll ship from within Argentina and you'll avoid the customs headache

I found a pair of shoes which I brought from Argentina -- it's 44 Argentinian and my usual US size is 10.5 or 11.

I second this. I am 10 or 10.5 in USA and 44 here
as always, YMMV
