it also doesnt have that annoying arch support thingy that many other flip-flops have. The first time we went out to a physical store to measure my daughters feet on a MERRELL chart they supply to their distributors. I tripped every step I tried to take. gonna order something better LED’s are on when in case, as shown by picture, but when out of case LEDs go out & the earbuds do not pair together. I’ve only worn them about 6 times now, but they were perfect for my camping trip in Lake Powell area. The sound is nice and full, well-rounded. I will update my review after those arrive. In the end weve decided that the S2 is the one we will be giving her, purely because we prefer the styling of them (they are a little more unusual in their design compared to these) but to be honest both perform really well for the cost. The cabinet took so long to put together.
