Kneesavers will take out that inward pull all bikes have at the bottom of the pedal stroke which , with clips, will become important to your knee, ankles & hip joints.
On a personal note: I think that clipless is dumb on the street but not everybody believes me.
Sigh. Can you provide evidence that the average person needs a pedal or crankarm extension with clipless? Or is this just another "opinion" you are presenting as fact, ala your previous claim that all fat cyclists have problems with blood circulation?
