Do you feel spinning shoes are beneficial?

I take spinning class 1x a week for the past year, so the instructor said I may want to get some, but I haven't spent the $ because my feet don't bother me when I spin and it's not like you can use them for other activities. What is the benefit supposed to be? There is a girl in my class who bought some using a gift card and she said her's were pretty expensive. The first time she used them in class she spent the first 5min messing with them and said it was hard to get them to click into the pedals. She stopped going to class shortly after that, so I am not sure if she likes them. I will be interested to see what feedback people have.

My dh has them. When he spins he is a maniac and stands up the whole time. His legs fly on that thing. The shoes really help his feet to stay on the pedals.

My toes were killing me after my class and I was wondering if the shoes would help that.

Maniac would be how I would describe the class I took on Friday.. lol!
