Thank you for all the recommendations.

I’ve started to use plantar fasciitis socks when I wear my Ariats. So much more comfortable, that extra support really helps.
I’ve put the insoles in my deck shoes and wear them around the house, again so much more comfortable.
In addition to the above I’ve started to do the exercises on the step, it was a bit 😱 at first but definitely getting easier.
This morning was the first in a long time that I didn’t have to hold onto the bed when I got up, just a 2/10 lameness I’d say. Thanks again you wonderful lot.
