The problem with these shoes was that they were loose and coming off.
I could not walk comfortably so I thought to make ankle straps.
I made a pattern and traced it on the relics of an old pair of boots:
...cut it and glued the sides...
...glued it inside each shoe...
...used ankle straps I had from some old flats..
...and the result:
Now it's absolutely comfortable and I like their style more.
Thanks for reading!
