I'm in the same situation as you - just ordered a 38 in grey suede when I'm a true 37. I took a 38 last year in the leather single soles, and the fact that I tried on the canvas double soles in 37 but really really struggled - they were so tight - makes me hope the 38 suedes will be okay ... 😔
Good Luck to both of us haha
I should get mine wednesday or thursday. We shall see
