Who was the marketing genius that said we have the best selling sandals, very popular, very reliable and durable, people love them... I know let's add a strap and choke her big toe! And which body approved this brilliant idea? Waste of $95. I hate it when my thumb chokes. Very uncomfortable! I like my Z1 chacos but not the Z2 with the big toe choke strap. I've tried and tried but I just can't wear them. They found the house at the bottom of the closet. Unfortunately almost $100 was spent.
