The Ultra Flex Bootie design was based on our original, low profile, sensitive Flex Bootie. We have improved the fit with an updated last shape and added an incredibly secure Velcro closure system, while retaining the high sensitivity. Stitching lines have been optimized to prevent chaffing from foot straps. The rubber laminated sole gives all the protection needed while also maintaining the best flex for ultimate comfort.
