Apologies for answering not been asked ;) but ... the foot needs a proper support and correction all the time - so, running shoes, everyday shoes, home flip-flops (like Hoka Recovery Slide - excellent arch support and amortization, for a flip-flop) etc.

Why putting a stress over a tendon if stress isn´t necessary? Leave the stress for a tendon for special occasions eg. running :) it will be stressed anyway, even with orthotic insoles inside a shoe.

Edit:
I´m convinced, and my physio is sure, that all my ankle problems started, as years and age go by, because of my high arches lacking proper support. Thank´s to the proper insoles I don´t have problem with inner side of ankles for years, now, only Achilles :/

Weightflex are changing the foot support inside a shoe considerably, my feet felt more stable & comfort in a neutral shoe with Weightlex, then in a stability shoe without insole.
