I use the Nashbar Ragster as my primary bike shoe year round. Even on week tours as my only shoe. I have about 8k on them. Road, gravel, and MTB. Moot point, Nashbar and that shoe are gone.
Following the thread because of that.

Nashbar didn't make anything really. Can't say if Exustar was related somehow but the SS503 is the closest in overall design.
