I have been walking SO much more in lockdown - avoiding public transport, and going on long walks for exercise when the gyms and pools are shut.
I so enjoy my walking fitness now that i just couldn't contemplate anything that would hinder or hamper me or make me feel less free and active.
I have never liked the look of heels anyway - the heel 'thing' sticking off the sole looks bizarre to me. And I am tall so have never appreciated them for extra height.
Fair play to anyone who loves and wears them, but I have never worn more than a 1.5" kitten heel and won't be starting now.
