I bought these sandals the day before I left for an holiday in Europe. Timing was poor but had been looking for them for months. At the outlet they felt comfortable and the adjustment cord allowed a good fit. I was worried as there was not time to break them in. Long story short no break in was needed and they were my "go to" footwear for the full two weeks of vacation. We did about 25km per day walking and they show no signs of sole wear or cord wear.I would love them to make a full "shoe" with cord all around.
