DH and I use them after cycling. Usually the full length tights although DH has just purchased calf sleeves as sometimes he finds full tights too hot.

They work, really do relieve the ache in your legs and help with swollen legs/water retention issues. We wear them to bed at night if we have to ride two days in a row, or when we cannot get a massage.

I am not entirely sure about the claims that are made about performance and wearing while exercising. NZ Consumer magazine looked at scienetific studies and didn't find any evidence of that, but did find evidence to support recovery.
