Wie fallen new rocks aus?

At the beginning of the year I bought 3 different shoes from New Rock. All in the same size. One pair fits perfectly, one is minimally tight, but still well portable and the other pair is minimally too big. (This is “normal half shoes”)

With the boats I have always been lucky that they have been super-fitted, with I myself have an intermediate size and therefore vary between 2 sizes, just like you. The larger size has always been successful at 4 pairs of boats (but distributed over many years). I tried the smaller size 1x. It can be worn, but is not pleasant in the long term.

So my recommendation, take the 39. You can do tricks for the trouble. Too small is definitely not recommended if you want to run longer with your shoes.
