OMG, I am (almost) an expert in foot issues...
Major problems in last 18 months that have even taken me to a foot surgeon for advice.
Things I have learned...plantar fasciitis quite common in peri as fluctuating hormones (grumpy ligaments, tendons) combine often with weight gain.
The impact on the arches is painful and persistent.
Game changers include insoles, supportive shoes (all the time) and very regular calf stretching.
I was told that flashes of pain across the top of the feet are connected to over tight calves, preventing correct placement of feet when walking.
I could go on, this has been my life, trying to walk without pain again
Also have lots of weird leg stuff also, massage and regular exercise help...
