I absolutely love my chacos; I had the last pair of classic Z1s for about 20 years. I assume they will work just as well. The only problem was that the ratchet strap was too long and had to be taken to the shoemaker to be shortened. Approximately 2-3 inches of strap will stretch when tightened. Shoemaker took a step back to make up his mind. Cheap fix but I didn't plan to spend the extra $12. Great sandals, LOVE THEM even with the extra strap
