Wondering about this as well. Finding the original Achilles to be a bit tighter than the vintage Achilles I got last year (same size).

I know this is an odd answer but it's reality.
This also may be a bit odd of a question - but - have you tried lacing them up yourself? I've found that "factory" lacing is typically very tight. It's common for me to relace with my foot in the shoe to get a better fit. I also always wear very thin socks with my Achilles.
Just some more food for thought.
I'd check out the repellent from Jason Markk.
End discounts code normally "exclude" Common Project items. I've never seen them on sale at End.
42 should fit you. But chelseas do fit slight tighter than their sneakers. I'm the same sizing as you and I wear all CP in 42.

I'm about to order a pair of CP achilles low triple black & is confused about the sizing. I'm a 41 in Buttero Tanino (not to snug, not to tight).
I always aim for the correct length - that's 27 cm. It's the best way to get the right size in my opinion. But here's the problem... Common Projects don't list the cm-size. Can anyone help my?
