Sandal had nubs on inside sole which poked the bottom of my feet. Very uncomfortable. I hope this is a manufacturing defect. I ordered a 2nd pair hope they will work. Note other reviewer had similar experience. Stay tuned and I'll  update when I receive 2nd pair of sandals  Now I have worn for a few weeks the nubs are not as bothersome but I can still feel them. I like the style in the summer heat so I'm going to keep these. I'd say if you can find another brand with the same style that feels better on your feet - buy it. Next pair I'll be looking for something else
