Bristles r very nice n keep to shape. It seems every time I leave a critical review the company may replace it, but then wants me to change to a 5 star review because they replaced or refunded. The top fit great over my breast (form fitting but not tight) but the mid section perfectly loose fitting for me. Hear footsteps. Such a beautiful sandal! They are also very long lasting. So far (only one week) they have worked well. These earbuds have increased my productivity and efficiency. It is solid feeling and "feels" like it will last me a long time. The insole was super comfortable, but around the last mile of our water trek, the arch started to irritate my foot.
