In my opinion, these are the most comfortable of the 'sports style' casual trainers .
Part of foot lockers half year sale
These are the 360 model. They tend to be in special around the $150 mark. Retail is $250+
Couple of colourways available in most sizes
Update: black & yellow, orange and 'french blue' still available at $119. the rest are oos
Maybe not quite casual style though?
