Table 1: Classification of hallux purchase
GradeCharacteristics
GoodThe sheet of paper remains static and in situ when pulled
FairThe sheet of paper moves slightly when pulled, but tends to tear when greater traction is applied
PoorThe sheet of paper can be pulled out with minimum effort
AbsentThe paper slips out easily; it is not retained by the hallux as the pulp of the toe does not make ground contact

Hallux purchase is inferred by the ease with which a sheet of paper can be pulled out from beneath the pulp of the weight-bearing hallux.
