I did it.
I buy my wife shoes all the time. Honestly, I am not very good at it. I have the running shoes dialed in, thanks New Balance, but outside of that I'm like 30% success rate. I have a pair of sanuks and wanted her to feel like she is walking on clouds of fluffy cotton candy too - so I went for it. I snagged these and success! She loves them. They are comfortable, look good with a variety of outfits and they fit her well. I was nervous about the fit since there are not half sizes. She is a 7.5 and I went with the 7, only size left at the time. It worked out. I/she would recommend these.
