This is indeed what I notice right now, in the Flow liner, my toes are against the front fabric so I guess the 'give' might come at the heel, to give my toes more room lenght-wise?
So let's say I'm not using the cat, but the box cutter.. do I actually cut slits on the inside of my liner? I'm a little confuzzled, won't I be wrecking the material? Should I be doing this before, after, or instead of molding?
So many new questions
