Oxford-style lace-up shoes with a suede upper and nitrile

Walkway
A 201.5m walkway was constructed to provide a partially
yielding, irregular walking surface. The walkway consisted of
5-mm pile artificial grass underlain with 20-mm thick wood
blocks of varying sizes and shapes scattered over 2 layers of
20-mm thick soft foam rubber. Two markings were made on the
walkway 15m apart to designate the trial distance. Participants
were also tested on a level corridor. A diagrammatic representation
of a participant taking the test is shown in figure 1.
