I love the split sole as well, split soles dont typically have very good arch support, but these actually have pretty good support. Ill update durability in 6 months or so. Everything is crisp and clear and LOUD. the headphones also feel rather flimsy I must say, definitely NOT premium. Took forever for me to find a good shoe rack that was everything I needed. Why I give it a 4 total. It holds more than 40 pairs+. So angry this happened, its been 3 days and the raw spot from the blister is finally healing . Im going to try to bend the upper heel back so it wont cut me again. Nothing outstanding about the slipper, but it appears to be well made.
