My mum always made me & my sister wear Clarks shoes through school and we both have really straight feet & toes now with no bunions & corns etc, so I always vowed that my kids woudl be subjected to the same.
I got DS1 his first shoes at the end of jan when he was 9mths as he was struggling to crawl on our hardwood floors and kept slipping - Clarks do crawlers, cruisers and then walkers. Also i hoped it would help keep his socks on whenever we were out as he would find shoes harder to take off than the softies he had (no such luck he quickly worked out the velcro straps)
Although he could stand up he was nowhere near to crusing even as he could barely crawl and so we got the crawlers which have soft bottoms and sides with grippy bits on the fronts.
I've only just had to buy him a new pair last weekend as despite taking him religiously every 4 weeks for a refit his feet hadn't grown and so although he's been walking for a couple of months now, he's been in crawlers all this time and so has missed out cruisers and is now in walkers.
Again he tends to slip over easily on our hardwood floors if he is just wearing socks, which with this weather he needs to be, so he does wear his shoes quite a lot. But I do try to make sure he doesn't wear his shoes unless he needs to.
Another point to consider is that their feet get wider as they start walking, DS went from a F to a G fitting, so it may be worth waiting till your DS is walking a bit better
We've just bought DS wellies for when it's wet - he loves walking in them...
Finally sort out an overdraft before heading to Clarks - you'll need it
