The shoes are comfortable as well as the straps. Im doing more road now and I wanted something for long runs. Out of the box, I was a bit surprised at the weight of the scissor arm. 5, but lately have had to order 9s in almost everything. 5 mm to 2. I could probably have taken a size 6. Another feature to consider is, they do look pretty cool and a lot more futuristic than the look of someone just cut the wire off of an oversized pair of ear buds. Well built and would buy another without hesitation. Sorry I just knew I was not going to be able clean all of that out of there. My big toes rub against the material in front.
