hockey skate was less like a rigid ski boot and more like a

flexible running shoe?
In October of 2012, Lachaine et al released a study that
examines the different body joint kinetics and kinematics
(the study of motion and its causes) while wearing a standard

hockey skate and while wearing a modified hockey skate. The

modified hockey skate has an altered tendon guard (much
looser than a regular skate) and eyelets, where the laces go
in, to allow more ankle movement during skating (Figure 1).
What were the results? Figure 1: a – represents standard hockey saktes, b – shows

modified skate allowing enhanced dorsiflexion and plantarflexion

Participants using the modified hockey skate demonstrated a of the ankle (lifting toes and foot towards and away from the shin
