There are literally hundreds of neutral wedges out there right now. I know, because I am also looking for some. I'm not sure how many will fit your "coverage of the foot" requirement, but check Nordstrom and Zappos to start because you can narrow those sites down quickly to search by style/color/etc.
Also, these are similar in color and style.
