Poor quality Skechers sneakers at Sneaker shed

Disappointed in the running/walker sneakers I bought in March 23, took it back obviously not in 3 months as it bit a distance from where I live. Both pair sneakers are bad. Bad poor sketches quality makes me wonder of the store is selling legit products. Was referred by someone that also do Parkrun with me as I suffer from plantar farciitis thought ill get something long lasting at least for more the 5. 6. 7 months lbyt the manager attitude made it clear I wasting my time and after my first communication with the regional manager assistant that I must take it back to the store they'll check it out ect but I dnt think that it ever reach the dept to do it as hardly 3 day I was contacted tp say they not exchanging it due to time frame of months know I would like to know when do things ever break in the guarantee/warranty month
