Trick or treat ?

I’ve got some new (to me) trainers from Vinted. The problem with these trainers is they are incorrectly sized so a load of people are selling them. I was fortunate buy but a pair from a shop a few weeks back, so tried them on and realised with this brand I am definitely a size 7 or even 7.5. My usual size is 6. I’ve been scouring the second hand market for some nearly new trainers in the same brand/ design and found these beauties. I’m wondering if the seller was getting rid of them because of the very uncomfy stone lodged hard in the sole. It took me 5 mins to try and get it out using an orange stick which then snapped! Screwdriver to the rescue! Amazingly the trainers show no damage or sign the stone was there. It’s a definite design flaw as my other trainers occasionally collect big stones but they are easy enough to remove. So fabulous to have found trainers that actually make me want to run again!
