5 just in case (there’s nothing worse than overhanging feet in sandals! I have 3 pairs of Fitflops bought over a span of about 5 years. They are very durable and well built. Otherwise, the binding would rub my heels and also feel the bump. 5 months already and not ran out of the ink it came with. I prefer reading product reviews from customers who have been using the product for some time rather than "Its so pretty right out of the box" reviews. I would recommend ice cleats since the soles do not have enough grip for ice. Imaging is pretty good, dont have much to say about. This results in some odd mounting configurations. But its pretty sturdy.
