BOOSTER STRAPS SUCK... if you have booster straps you better not ever land backseat or they'll hurt way worse then normal... the key to shinbang is rest, when your shins start to hurt take it easy and hit some rails or land switch on jumps... if you catch it early and dont keep hurting them your calfs will strengthen and you'll be able to ski more often without the problems of shinbang later on in the season, i had bad shinbang earlier in the season, then i took it easy for a week loosened up my boots and skied with them as loose as possible (around the upper ankle and shin) and have not had a problem with my shins since.. and ive skied hard 7 times in the last week and a half...
