These really are some of the most comfortable shoes, as well as stylish that I have had in a long time. Some quirks / minor issues:1) The "starter" mini tripod stand isnt quite up to the job for the weight of this mic. I actually tripped when one came off--a broken toe resulted. There is a nice tread pattern on the bottom to help with secure footing when traversing rough and uneven terrain. Two days later they were two sizes too small. I AM GLAD I DID! The instructions said that you have to loosen a bumper bracket to install the bolts but i found this to be false. I havent had any bad experience from my usage. 5 inches, whereas the radius on the top is 12 inches. 5 in big kids and I ordered a size 7 for him.
