The only bad thing is there's no support in this flat. But I can easily walk 2+ hours at a moderate pace without pain or fatigue in my feet. I love this flat it's perfect for everyday, office, dressy and travel. From day one I have never gotten a blister on any red spots. Mostly because of the scrunchie design of the shoe. Also I wear no show socks in black but I keep it above the line of the shoe or tights/nylons. And the few times the sock does slip it still hasn't irritated my feet. I don't have a picture but the product picture speak for themselves. I ordered the to suede like fabric in a 8.5W and they feet perfectly although my foot is extra wide, sometimes my pinky toe slides off the sole at times but it's not a bother or noticeable unless you step in water. That is the only reason I know since these flats are not water resistant or proof I would be careful on wet areas or weather heavy days. So far my feet haven't gotten hot/sweaty or to cold but I've never warm them below 45 or above 70 yet. But I don't think I'll have an issue with hot weather. For cold it might be a problem below 30 or 40. I already have plans to buy many more colors and I have my eye on some of the colors out of stock, so hoping they make them again. I do think they are worth way more than the price. But I hope these never get retired or sold out I will love them into old age. I need to mention the longevity, I've had them for a few months and have walked on many surfaces and have never worried about slipping or falling. I just avoid rain and puddles, but they still look brand new even though I have walked on wet grass several times. And I have yet to need to clean them so far. So truly happy with my purchase.
