As others have said, choosing a saddle because of its colour or shape is wrong, especcially when it regards Fizik saddles. All the models are made in just one size so you have to choose the model which fits your sit bones. For example, an Arione is a 132mm and an Aliante 140mm. I had an Arione and got on with it well, till I had a bike fit and found it was the wrong size for me as my hips were rocking whilst pedalling, they fitted an Aliante and it supported my sit bones better and prevented the rocking action making pedalling easier. Out on the road, the Aliante was a far better saddle and distances of 200+ a day was well in the comfort zone whereas on the Arione about 150 was enough for the day I found and fitted them to all my bikes apart for one which has a Brooks.
