Runners knee- looking for more answers

kinda. the supernova has kind of a varus wedge design to the sole. although it is a neutral shoe, it helps to provide a little bit of support to the arch so that your foot does not roll excessively inwards as you start to fatigue. the midsole in this way is slightly thicker on the medial side than the lateral side. so, in this way, it helps stabilize your foot.

when you move to other shoes, that wedge is generally taken away, which could cause problems, and for you it has. the left side bias is most likely due to an imbalance somewhere in your body, whether it be a leg-length discrepancy, a hip misalignment, or slight scoliosis, or arch difference.

to solve these problems, you absolutely need to do three things: build a strong core, strong hips and glutes, and strong lower legs, feet, and ankles. i can post some exercises if you are interested

as for the shoes, just stick to what works. the supernovas (now the solar glide) are very good shoes, and if they work for you, then you should continue to use them. however, you need to build a strong body that can compensate for whatever imbalance or weakness you may have that could be causing the pain, because ultimately it's what kind of body you put in the shoe that will decide your performance

I highly doubt it's just the shoes. A lot of time runners knee is due to muscle imbalance/weakness. Are you doing any strength training?

I have plantar fasciitis in both feet. I could feel how comfortable these sneakers were from the moment I put them on - EVEN BEFORE I STOOD UP!!! I could feel the heel of the shoe cuddling my heel. I can not bear to wear anything but my orthofeet shoes! I like the hammer toe for toe comfort. Fit is great. I like the colors and the mesh.
