Well after asking this question I didn’t listen to the advice about sizing up! ordered the size G-form recommended and the results were as mentioned, a little tight resulting in my feet feeling numb after 30mins of wearing around the house. Sent back to G-form and got the next size up and they are perfect, the pad is every so slightly big around the knee but not overly so to cause a problem, really comfy and the turn around from G-form was real quick getting them back within 48hrs from when I sent them back.
On another note does anyone know the fit of the elbow guards, is it recommended to size up? (I will listen to any advice this time!!)
