I needed a pair of shoes for my spin class. Wanting to support a local business and hoping to get good service since it was my first spin shoe purchase I went to Art's. The young man who helped me out seemed semi-knowledgeable and I purchased a pair of shoes. He assisted in identifying cleats and two men installed them for me. This was exactly the type of service I was looking for, but unfortunately the cleats did not work on the spin bike at the gym. I wasn't happy about having to return the cleats since the whole point in going to a physical store was to make sure I made the right purchase. When I went to return them the young man working the counter said that I couldn't return them because they were already mounted and used. I purchased the cleats they recommended, they mounted them for me, and I don't think attempting to clip them into a bike pedals qualifies as used. I realize there are different types of pedals and cleats which is confusing to me and clearly the young man helping me out was just as confused or didn't have enough information to make a correct recommendation. Whatever the case, at the very least it would have been nice to be informed that I wouldn't be able to return the cleats once they installed them and that the cleats may not be compatible with my gym's spin bikes.
