I suppose someone can repaint them. Bass felt virtually non-existent (Im not a "bass person", just for the record). I may opt to do so anyway as I purchased this as a gift and receiving a replacement a week from now will be of no use to me. Some of the lads I cycle with spent ?70 on different systems but this is as good if not better. This is an excellent and comfortable house shoe! For the price, this is a steal. The 8s I initially ordered are about the size of the Crocs size 6 he wore last year. For me the medium may be a better fit. This buy here doesnt even tell if its Optional until youre package comes in with the box saying is optional. 5 to 2 size difference between number sizes in these shoes.
