I wavered on buying these for so long and now that I have them, I'm sorry I waited! I haven't worn anything else since I got them. Shipping was so fast! I normally wear an 8.5 US in most shoes, got the W8 in the Feder and they're a perfect fit. The material is soft and pleasant but not stretchy. They clean right up with my normal clothes brush. They're so comfy, and I've been wearing them all day. This is my go-to shoe for the summer, definitely a good investment!
