I broke down and bought a pair of calf sleeves. I've really been conflicted about this purchase as (a) I didn't want to look weird wearing them and (b) I didn't really know if they worked. But after three good reviews from people I actually knew I thought it was time to get some.
I bought the CEP black calf sleeves in the smallest size they had available. Why CEP? Well, it's what was available at the local Road Runner Sports and because Dave and my dad love the socks. I got the black ones because I tend to rub my feet against my calves when I run and because sometimes I might pee on myself while running a race. :) White obviously would not have worked.
I have worn them now for two long runs: 13 and 14 milers. And I'm not sure they did anything at all. I take that back. My upper calves felt great after those runs, but my lower calves were extremely sore. I tend to be a forefoot striker as the pace picks up so when I get to the recovery parts of my runs, I notice how tight my achilles/lower calf is. The calf sleeve did nothing for this. I don't know if wearing the full socks would help this but that's not something I'm willing to try. I'm kind of picky about my running socks so I prefer to wear them. The calf sleeves have also helped keep my lower legs warm during these winter months, although I'm not sure they were meant to be worn as leg warmers. I am going to continue to wear them during my long runs at least through the marathon and then decide if I'll continue to wear them. Heck, they might help me on the bike too!
