I've been wearing the Adissage model from Adidas for a few years.  The nubs on my last pair was now mostly gone so time for a new pair.  I saw the Calissage has good reviews, and the nubs are bigger so I was hoping they'd be more durable (recent reviews on the Adissage show they're lot less durable now, nubs falling off fast), so I thought I'd try the Calissage.

The problem I have with the Calissage is they're not form-fitting like the Adissage--no arch support at all.  The Adissage is contoured to the bottom of the foot at the arch and under the toes.  Also there is hardly any massaging effect, maybe this is just because I'm used to the much more aggressive massaging effect the the nubs on the Adissage. No, actually these can't offer good massaging effect: it's not form-fitting and so there is too little foot to slide contact.  It can't massage what it doesn't touch.  This is basically just a cheap pair of slide at big brand prices.  Guess I'm just outta luck with Adidas now until they go back to using more durable materials for the Adissage.  I won't be buying another pair for a while.
