I just got myself a new pair of Converse Chucks (Hi). Ive never worn these type of shoes before

(what I meant was like almost no padding on the soles haha)
Do you guys have any ideas why I'm experiencing a sharp/stabbing pain on the part marked red? It's like as if the muscles there are stretched to the fullest extent. It happens when I bend the feet when walking
Could it really be the fact that the shoes have no padding? But cannot be wat... at home nv wear any shoes no problem at all. And not that I walk 20 miles then pain, it's as soon as I got down the lift, can start feeling pain alr.
The really weird thing is that all my other shoes (8 pairs +) no prob.
The last time I encounter this prob was like nong nong ago, that that time wearing tight sneakers or slippers.
