Merrell sandals have been well reviewed by many, and I'll simply add my own enthusiasm.  I bought these when the previous pair I'd been wearing (and bought in a store) were finally so dirty I felt bad to be seen in them.  But I'd worn them at least 7 years, and had NEVER had a pair of sandals that were so comfortable and had such good support.  I could wear them all day and be sorry to take them off.  It took me a couple tries to find the right style to replace them over the Internet, but I found quickly that the only shoes I wanted were Merrells and I settled on these, and haven't been sorry.  The support is excellent, the fit is perfect.  The wrap around the ankle works, but is time consuming to put on.  A small complaint, and my only one.  I love Merrell shoes!
