tjkirchJust got sizing info from Chevalier. This is what he said:
Sizing for the Longwing-
True to size.
You can compare it with converse all star sizing or other low cut shoes, but not sneakers like Nike or Adidas.
tjkirchEvery larger size has difference 0.8-1.0 cm in length.
Example :
Size 42 is longer around 0.8-1 cm than 41.
Hope this helps! I have also extended the buy 1 day. :)
