SportsDirect.com review: Trainers nike defyallday sn10. Style 131072 (white)

Purchased trainers on 9th December 2024.
Used once in damp conditions, right trainer leaked water through sole, not worn since.
Returned trainers to Southampton store beginning January, supervisor employee No 579457 refused to exchange or replace because he could not see where dampness entering.
I stated cannot replicate by holding the trainer the movement of sole when walking with continual bending which could open-up a small void where water could enter or possibly a small air hole, trainer has a quality issue.
Disappointed with a response from supervisor saying that i must have walked through a puddle and water entering from sides above sole which is totally incorrect, dampness is under the sole of my foot and i certainly never walked through any puddles.
Have purchased many trainers from Sports Direct over the years and never had a problem until now, disappointed with after sales attitude and service.
