In my country, Lidl had kids' trainers for 5.99€ a pair on sale today, "while stocks last". You best believe I basically ran there after dropping the kids off at kindergarten
managed to get two pairs for each child so that’s 4 pairs of trainers for about 24€! 
Most of their shoes and clothes are either from Lidl or Aldi. It's actually quite good quality mostly. For example, I bought a winter jacket for my oldest when he was about 2yo. Not only did he wear it for a couple of years, his younger brother then wore it for another few years! And it still looks ok. I don’t remember what I paid for it but probably about 10€ so I really got my money's worth!
