Upper foot/Achilles pain

Thanks for the replies chaps. When we were manoevering around the yard my foot was braced just touching the clutch due to a lot of toing and froing. …and my footwear was pretty tight AND I was nervous so maybe I need to adjust a few things and take the short term pain.
Could anyone tell me if there is a formula for correct seat position in relation to hip/knee angle etc?

Thanks again :slight_smile:
