Wiggle has a big sale on at the moment, the prices on the Adidas Ultra Boost ST (both womens and mens) vary depending on size, but some are much cheaper than normal Australian pricing.
If you throw in a pair of socks the cheaper pairs will have free shipping. I'm a huge fan of Adidas Boost runners, but here is a review if you're curious: http://www.runningshoesguru.com/2016/02/adidas-ultra-boost-s…
Last time I checked prices and sizing for the mens worked as follows:
Blue:
UK11 - $72.26
UK8/8.5/10/10.5/11.5/12 - $113.29
(all other available sizes are around $180 so not really a bargain)
Red:
UK11/13.5 - $113.29
Black:
[SOLD OUT]
Good luck and I hope you find your size!
EDIT: The womens Ultra Boost ST can be found at http://www.wiggle.com.au/adidas-womens-ultra-boost-st-shoes-…
EDIT2: Updated the sizes for what's left, happy running everyone!
