I have an uncomfortable foot, 13.5 B. Size 14 shoes are usually too big for me (especially wide), and size 13 is too small. I tried Ecco a few years ago and found that a size 47 fits me perfectly. This is my fourth pair of Ecco Yucatan/multisport sandals and is everything I wear from mid-May to mid-September (and I have tan lines to prove it). The support is great, it fits my narrow feet well and they are comfortable. I wear them on my daily 2.5 mile walk with my dog, wear them to the park, wear them anywhere convenient. The only downside I have with both of my pairs is that the heel strap is too short. I usually just undo the heel strap to put them on and take them off. But on both of my pairs, the heel strap often slips out of the loop/buckle on the other side and has to be "put back in". This is not a major problem or a product defect, just a matter of convenience.
