After advice on here I spend a lot of time stretching. Calf stretches, glute stretches but the key ones (I think) for me have been –
Kneeling on the floor with tops of feet facing the floor and slowly sitting back on my heels
And
Standing up while placing one leg slightly back with the top of yours toes curled under so they touch the floor. Apply downward pressure and you should feel the stretch.
Also
Stand with feet shoulder width apart and roll your feet outward so you’re standing on the outside edge of your feet.
All these were advised by guys on here. I joined this thread on page 127 if you want to look there for advice. It’s helped me massively.
