Excelente calidad producto acorde precio valor, totalmente recomendable Highly recommended- best Shoes we have bought for our daughter in a long time. I would expect them to last a bit longer especially for $30 dollars. They are comfortable only when I sit and stand. I would say if you are using it for skinnier tire bikes that are not heavy, it would be a great rack. They also get very sweaty without bootie socks and the insole is rough/not comfortable. I cant believe how good these are. They even apologized for them being so small, though the dimensions are clearly on the description. I took a long road trip a few months ago and needed this for 2 large sea kayaks. For example I have just the logo to do a lighting effect while the other keys are static.
