All Blacks offer 'honest feedback' for adidas at the sports apparel manufacturers' HQ in Germany
The All Blacks hope their "honest feedback" will help adidas make them even better gear in the lead-up to the next World Cup.
Kieran Read and his team have visited their apparel and footwear sponsor adidas' German headquarters in Herzogenaurach after completing their northern hemisphere tour.
The players were assessed by biomechanics, physiotherapists and sports scientists and measured up by tailors for high-tech uniforms, TVNZ reported.
A big All Blacks banner greeted the players before they were invited into the company's Athlete Services and Future Sports Science labs.
* All Blacks' vehicles auctioned
* Back to the pack for All Blacks?
* Hansen: I'm so proud of the boys
* All Blacks to hold 'wellbeing' camp
* Reason: ABs far from the greatest
* 'Satisfying' - ABs coach on 13-1 in 2016
* Barrett finishes with a flourish
Fullback Israel Dagg was impressed with the "crazy" level of detail with jerseys designed to mould to an individual players' body.
"It gives us every opportunity and every possibility as best as we can," Dagg told TVNZ.
"You actually don't think what goes into making them until you get over here and see it all."
Dagg quipped that lighter boots helped his goose-step, although he said that the opposition were "getting on to the goose" and he might have to find another trick.
World player of the year Beauden Barrett said it was important for the players to be comfortable in games and during training.
"It's about giving them the honest feedback so they can make a better product."
But the All Blacks won't be getting their new gear instantly.
It will be another two years before the jerseys and boots are ready once further adjustments are made when Adidas technicians visit New Zealand in 2017.
