I just tried on the treks, I found a store near me called Primo Comfort Footware. The people were great very helpful, and extremely patient. My first impression of the treks was "WOW these are tight! Too tight..." I also noticed how soft, and luxurious they felt. They felt amazing and the 45 fit my feet perfectly, but there's still the problem of the tightness. I didn't by them today, I want to here how much they stretch first.
An interesting thing I noticed is how the sizes vary due to the leather. I wear kso 44 on a daily basis they fit my feet perfectly. In the treks 45s are perfect just tight over the top of my foot right behind my toes.
So my question is will the leather stretch? And if so how much?
