Very comfortable! I have back problems and standing for extended periods of time causes alot of discomfort. I'm a Social Worker at a dialysis center and there are days when I'm on my feet for long periods of time. I have been wearing comfortable tennis shoes, but felt I needed a Nurses shoe that was made to take the strain off the back and hips. These certainly make a difference in how I feel at the end of a long day. BUT, I wear a size 8- sometimes an 8.5, depending on the shoe. The 8 was so big on me that my heel came out of the shoe when I walked. These don't come in 1/2 sizes so I was scared a 7 wud be too small, but it fits me perfectly. I would've given 5 stars, but if u order the size u normally wear, you'll have to send th back. That's inconvenient. So, make sure u order a size smaller than u usually wear.
