Update: Jan 19 2021: I accidentally dropped one of the earbuds into the kitchen sink and it fell into a bowl filled with water. Im not complaining because I know that will change once I break them in, but I do wish they were easier to take on and off. Have worn these shoes on 4 continents and still looking and feeling like new. These are truly rubber on the bottom, so just perfect. They are so comfortable and I love my husband for buying them for me. That is the only down side of my Chacos. The 3? gusset allows for more than one clothing article to be placed in the bag. I would say I wish the sturdiness was better but it helped for what I needed it for. so 3 colors tops at a time and theres no direction or travel effect. The chrome finish look on the inner side above the ear cushions and around the headband extension joints are a fingerprint magnet nightmare!
