These were recommended to me by a person who is knowledgeable on sound quality/headphones. These crossbars also have an extra plastic lip on the front crossbars which wouldnt allow the SUP carrier to sit flat even with the longer bolts. I have many Clark?s ?bendable? sandals , in the Lexi heel height. Quality on this was good, however, I got this after reading it fit well for the Reverb G2. She wears them everywhere and you can hear her cute little feet patter around the house. 8" bag thinking the other would be too large based on the images in the ad. super cute! Quality is outstanding! Buy them with confidence. I bought this and put it on the bottom shelve of a bookcase and it works great to store wine.
