Dean Karnazes Plus Footbed, Signature Series

The DK+ footbed allows you to use the Nike+* iPod** Sport Kit (sold separately) with any shoe without having to modify and possibly damage your existing footwear. The DK+ footbed still provides all the same benefits of custom support, industry-leading Softec cushioning and anti-microbial odor protection as the original DK series footbeds. Please note: The DK+ footbed works best for people who have medium to high arches in men's sizes 8 or larger and women's sizes 10 or larger. If you purchase any size DK+ footbed and are unsatisfied for any reason, return them within 90 days for replacement or refund, no questions asked.
