The Adidas Ultra Boost trainers seem to be popular right now, so hopes this helps someone.
Wiggle are selling the ST (stability) version of the trainer for £58.50 in black and blue, although not all sizes are available. superb comfort, but for me, a little hard to justify at the £130RRP. Great reviews.
