Claims20
A sole structure for an article of footwear, the sole structure comprising:
- a plate having a first side configured to be ground-facing and a second side formed on an opposite side of the plate than the first side, the plate comprising a polyolefin-based first resin;
- and
- a traction element extending from the first side of the plate and including a stud tip, a stud shaft extending from the stud tip and including a frustoconical shape having a proximal end disposed at a junction of the stud shaft and the stud tip that defines a smallest cross-sectional area of the stud shaft, a plurality of first retention features extending from an outer surface of the stud shaft, a plurality of second retention features extending from the outer surface of the stud shaft, and a first planar surface extending between and separating first retention features of the plurality of first retention features from second retention features of the plurality of second retention features, the traction element comprising a polyurethane-based second resin.
