BRAND NAME NEW, NEVER WORN - Newton Sir Isaac S running shoes, size 111/2 Men's. A moderate stability shoe for high mileage running.

　　I bought these from the Netwon Running Lab in Boulder and then never wore them due to an unrelated injury soon after that. These are never used and genuinely brand-new. I'm offering them as I've got some other shoes now.

　　This shoes offers new for $149 new, I'm asking $85. Contact me with any concerns.
