Communication between myself and seller very fast. Bonus - she likes to wear them so I know they are comfortable. I really like the size of the mouse, though the ring-finger grip is a little awkward to get used to. Very comfortable for walking long distances/hiking and everyday use. Ive tried equalizers. For direction changes, these are still better than the original Ultra Boost shoes, but not great for any cross-training or trail running type movements or surfaces. Once I put them on, I noticed that the toe of the flip flop stuck out further than any other flip flops I had. Had i received 100 i would?ve given this item a 5 star. My foot no longer slides, they are extremely comfortable and warm. With these though, I can put my phone on the kitchen table and walk into other rooms and still have an uninterrupted signal.
