So in the end I've decided to pull the trigger on these. I approached the Blushield 5's three times and I really wanted them to work for me, but the shape was just not for my feet. The shape of the toe box was too angled and my toes suffered immediately. That's why I was reluctant about the Torneos, because they seemed to be an upgrade with only slight changes.
I am pleasantly surprised, however. The toe box is definitely more straight, it does not bother my toes. Compared to Lotto Raptors (I've been playing in them for a year now, my go-to shoe), it is similar, maybe only slightly narrower (the outsole in the Torneos is around 4 milimeters narrower in the forefoot), but still very roomy and comfortable.
Length wise, 11 US in Raptors and in Torneos seem just the same. I've measured the insoles and they are the same length. The Raptors in general are slightly longer, mainly because of the outside foam at the heel.
Forefoot cushioning is more plush and detectable in the Torneos than in the Raptors.
The only thing that sometimes bothers me in the Raptors is the ankle collar, very stiff and high. No such problem in the Diadoras. Slightly lower and more comfortable, especially in the Achilles tendon area. Definite heel slippage however with standard lacing. Easily fixable with the runner's loop.
And regarding the weight: Raptors 450g, Torneos 430g.
So I am quite excited, for now I will wear them around the house, but I think I'll take them to the court too. I hope they will make me run like Fokina.
