Vaio - The reason the inner straps are that length is to accommodate a lot of different size feet/shoes. It's easy to trim them down if you find them too long but not possible to make them longer should they be too short. The reason we opted for the smoother seatbelt webbing is because through testing, we found it to be much more durable and stretch-resistant than rougher webbing. Also, the smoother stuff does less damage to your shoes.
