Leather Metallic Zip Chunky Trainers

Ordered these trainers from Jones the boot makers size 4 with a 20% discount. Arrived quickly with click and collect which was great as the postal delivery and returns is pretty rubbish. Trainers on the outside are nicely made and good quality, the lining is horrible thin plastic which makes your feet sweat. With no half sizes I’ve had to put some good quality leather inner soles in to compensate. Unfortunately on wearing the trainers on 3 occasions now two issues have appeared one I think is a potential fault. Because of the very poor quality lining no cushioning the trainers rub my toes made them very sore. The second problem is on the right trainer the side zip keeps coming unzipped no matter how much I try and adjust the laces etc it still keeps working it’s way down and my foot coming out of the shoe. So unless I can correct it they are going back as this is a fault. Definitely not worth the full price.
