Best part is they are under $30, for blue tooth! Also has a Anker engraved rubber/TPU top surface (inner circle) to help keep your device from sliding around. Full daytime is fine too. The straps fit well. I will move to another brand if need be for a perfect fit - even if it means moving back to "tighty whiteys" to do so. I am tall, and it is hard to find a heel that is more than a pump, yet not too tall, but these were perfect. This is one shoe I should have shopped for at a store, where I could have tried on both sizes before making the purchase, if at all. Its a good value for your money but these things shriek. It cut pretty easy. In addition to this, the buttons will feel extremely mushy.
