@Noodle421 and @Theteapotsbrokenspout , re both the Fracap Olas and the Fracap Ankle shoes, i wore both at home first with socks on and then progressed to walk to the local shops in them, again with socks - no more than a 15 min walk each way. I have found that they stretch.
I tried the Ankle Fracaps on in both a 38 (my usual size() and the 39 in the Cambridge store last summer and the 39 were definately too big. I have a difficult left foot (hallu rigidis which is essentially a stiff big toe which pushes the joint out) and it means I need shoes with a wider footbed despite my feet being very slim. I have found with both the shoes and the sandals that the leather is soft and it has stretched over time enough that the shoes have become very comfortable.
With the Ola Olive sandals it is obviously early days (I broke the tan ones in laast summer with very little effort) but I wore them around the house for an afternoon when I was moving around a lot, I drove in them (short journey) and I have worn them to the pub with socks and they have definitely softened to the point where I was barely aware that I was wearing them. I haven't worn them without socks yet (too cold obviously) but I am expecting that the wearing with socks will have nicely softened up the leather by the time the hot sun arrives. @Noodle421 , might this be an option for you?
