I had no problem walking in these versus a thinner heel. The wider heel is definitely more comfortable. Several reviews said to go a size up, which I did. I wear an 8, so I ordered a 9. They are slightly big, but not so big that I can't wear them. But I do think my normal 8 would have been too small. 8.5 would have been perfect, but unfortunately, they don't come in half sizes.
