Since, Repelling Stench seems to be such a hit, I've taken Bierhoff's suggestion and created a new weapon to use in conjunction with the Behold! The Razor Slip-On!

New Exotic Weapon Razor Slip-Ons

Razor Slip-Ons appear very similar to the above shoe, but with a razor blade protruding 1 inch from the sole all the way around the shoe. No true Razor Slip-Ons wielder would ever wield them in conjunction with socks.

Light Exotic Weapon
Damage: 1d4 slashing
Critical: 19-20 / x2
Range Increment: 10 feet
Special: Razor Slip-Ons can be flicked from the feat as a standard action that does not provoke an attack of opportunity. Additionally, when wielding Razor Slip-Ons without the Exotic Weapon Proficiency (Razor Slip-Ons) feat, the wearer takes a 5 foot penalty to their movement and a -1 penalty on tumble, jump, and balance checks. The use of Razor Slip-Ons as a ranged weapon counts as removing the shoes for the purposes of the Repelling Stench feat.
