I have very narrow heels and feet, and the Salomon F22s from 2010 worked for me 100% perfectly. After using them for two full seasons, they just started letting my heels loose.
I'm also in the market for new boots, but those Salomons were so awesome, I'm gonna stick with their products and looking to get the new Malamutes if I can find a decent price on them.
Salomon and also the new Thirty Two Lashed are pretty nice as they have two tightening strings for the upper and lower parts of the insole that I heard works great.
Hmmmmmm...been wearing 32 Lashed for six seasons now and am only aware of the one tightening string for the inner liners.
