I'm not familiar with Crispi's line. Are these 2 ply softer leather or 3 ply? I find my softer leather, 2 ply boots to be more preferable for comfort, but they will wet out in wet vegetation. My 3 ply, stiff leather boots generally will not. In wet vegetation, your moisture can't bead up and roll off which is the process your boots rely on. In that case, they will be prone to wetting out.
Things that will help:
1. Clean your boots diligently every single time you use them
2. Condition and/or apply waterproofing every time your boots get soak and wet
