I love the look of these sneakers but they are indeed a fashion shoe and not for the serious walker unless on a flat surface. I originally ordered the six which is my normal size and they were so comfortable till I was walking back down my hill walk when the one rubbed a blister on back heel. I figure this is more a problem with my heel than the shoe as the other foot was unaffected. Also it seemed the toe box is a little short and my toes were sore the next day. So I ordered the 6.5 and wore an ankle sock and bandaid on the affected ankle and they were great for the uphill part but my foot seemed to slide forward while walking back down tho my toes were not sore after. I will prolly keep these for flat walking and just to throw on and run errands as they are otherwise very comfortable and easy to get on. I think that that is an issue with sneaks that are not tie or have an adjustable bungee. I don't like the heavy regular sneakers myself so was hoping these would work for the hill. I will keep trying and see if it's just a breaking in period as I am a relatively new walker. They are ready to wear right out of the box tho for normal things. Not a whole lot of arch support. I did not find the toebox too large and my foot is a typical med size.
