- The Adidas PureBoost X TR Zip sports the floating arch, an iconic feature of the PureBoost X line, which serves to support the bottom of the foot.
- It retains the signature Boost midsole. This foam has been engineered to be more responsive and shock-absorbing.
- The shoe uses the same non-marking rubber outsole as the original PureBoost X TR. It exhibits similar attributes such as the pivot disc and the flex grooves. It provides traction on most flat surfaces and facilitates multi-directional movements.
- The most significant departure from the previous model was the absence of a lace-up closure. Instead, it features a zip-up mechanism that closes quicker.
A rubber outsole protects the underside of the PureBoost X TR Zip. This compound is high-wearing, flexible and slip-resistant. It is also non-marking which prevents it from leaving scuff marks on polished floors.
Flex grooves run the entire length of the outsole. They facilitate foot flexion and enhance traction. The tread pattern on this model supports multi-directional movements.
A pivot disc is found in the ball area. This circular structure makes twists and turns smooth and effortless during workouts.
The PureBoost X TR Zip employs a full-length Boost midsole. This specially engineered technology delivers more shock-absorbing properties than traditional ethylene-vinyl acetate (EVA) foam. It also boasts of a high-energy return which gives it that bouncy characteristic.
The lightweight textile upper gives the foot more freedom to move. The fabric is breathable and keeps the inside of the Adidas PureBoost X TR Zip well ventilated.
Synthetic overlays are found in the lateral and medial sides of the broadest part of the forefoot. It adds support during side-to-side movements. This layer is also present in the throat, the collar, and the back of the shoe and serves to protect the textile from abrasion.
A Zip-up closure is used in place of a traditional lacing system. It allows users to loosen or tighten the midfoot section in one fluid motion. The stretchy tongue is attached to the upper and delivers a close-to-the-skin fit.
The floating arch not only gives the PureBoost X TR Zip a unique look, but it also hugs the sole. It keeps the arch of the foot supported with every step.
