Hi have been looking for decent girls shoes and came across these reduced from £35 to £17.50 - red only though, all other colours are still £35. There are some other Umi's that have been reduced if you search Amazon.
John Lewis have these for £35, the patent ones anyway. Also Amazon do free returns on shoes, so I have ordered two different sized pairs just in case the sizing is out!
Hope this is of use to someone.
