Working in 12 hospital, I wore sneakers in general, but in recent weeks I had from the super bad midday feet and legs, I aidonc bought those fangs, and it's great, Just a little sore feet at the end of 12, because I'm not the first youth. So I took one size bigger in case the feet swell, and I did well, because even though I have a little swollen feet, the fangs are always comfortable. The small spikes on the inside of the sole are good for walking, that massages the feet and provides a feeling of well being. I will buy in another color for the house, for I have taken are white. this purchase is necessary to work in the medical field I recommend +++++
