The latest Structure from Nike followed in the steps of its previous version and simply lost some weight. Nike introduced some major updates for the 20th version and they simply trimmed some weight for the 21. This high-mileage, stability trainer for over-pronators is as slick looking as it is feeling under the foot. It hugs the foot through the arch and locks you in nicely in the heel while opening up to a wider toe area up front.
