There are a few styles that have just been added to the Outlet section of the website today.
There are a couple of First Walker shoes (boys and girls), and a few styles of boots, all between £6.50 and £8!
If you don't mind about not having real leather then there are some from £5 too. :)
As it's all clearance stock the sizes available are different for each style, and some are very limited.
I know you have to be very careful with small children's feet and they should be properly measured, and like most of you I take my kids to Clarks and end up spending £30+ on a main pair.
But once they're measured I get a cheaper pair for the garden/park etc.
These ones fit the bill nicely. :)
Free collect from store or delivery from £2.95.
I'll put individual links in the comments.
EDIT 04/07/14 : Some styles now out of stock, including those in the main link.
