Can somebody, ANY body, please tell me WHICH Chaco SOLE has the SQUISHIEST FOOT BED?  Is it the "Yampa", the "Colorado", the "ProSole" or the "Pro 1 Sole"???  Of all Chacos sole styles to choose from, I have noticed that the lighter the sole, weight-wise, the more cushion there is in the foot bed.  I just need to know WHICH ONE has the *MOST* CUSHION.

Thanks so much in advance for any feedback to this question!
