Not sure if I can pull these off

 I've been going to the gym 3-4 times a week and usually end each session with a quick 20 lap swim in the pool.  I'm bought these to walk in and out of the changing rooms etc.  I'm not sure if I can pull off wearing them.  2 reasons

1. I'm too old
2. My feet are more like hooves so I actually struggle putting them on

I'm willing to give it a go though.
