Knee pain on new trike

[Riding in Circles]

Pedals with a lot of free float are the answer, Frogs give you the most but the cleats can be a bit delicate, I use Time Atak with the cleats revered to maximize float.

Have you ever measure your legs? I have 1/2" difrence in mine.
But most people have a bit of difrence, you might need a washer putting under your short leg cleat or a insole putting in that shoe.
