Hi everyone,

sorry if this has been discussed before!
I was wondering how and when you would decide to use an extrinsic rearfoot post vs an intrinsic rearfoot post?
At uni we were introduced to the idea of a Kirby Skive as an intrinsic RF post when u have estimated the STJ axis. Is this the idea behind all intrinsic RF posting?

Cheers
S

ps I just fell down a hill when out running - a full on roll fall too :boohoo:

 

Thanks for those!
