Influence of Supportive Sandals on Y-Balance Performance on Healthy Young Individuals

Brief Summary:
The Y-balance test is a lower extremity, dynamic test performed in single limb stance that measures a person's ability to reach in 3 directions. The test is typically conducted in barefoot. The purpose of this study is to assess the impact of footwear on Y-Balance test scores. The investigators hypothesize that by improving alignment and augmenting muscle mechanics, sandals with medial arch support may improve Y-Balance scores.

Arm Intervention/treatment
Active Comparator: Sandal Other: Sandal
Subjectes will be scored on the Y-Balance Test wearing an Orthaheel Sandal
Other Name: Orthaheel Sandal

Primary Outcome Measures :
  1. Y-Balance Test Score [ Time Frame: Day 1 ]
    Anterior, Posterior-medial and posterior-lateral maximum displacement (in cm) will be recorded as the best of three trials for each supportive limb in barefoot, supportive sandal and flip-flop

Secondary Outcome Measures :
  1. Arch Height Index [ Time Frame: Day 1 ]
    An instrumented measure of arch height will be taken

Other Outcome Measures:
  1. Malleolar Valgus Index [ Time Frame: Day 1 ]
    Malleolar valus testing will be performed to assess the structure of the hind foot

  2. EMED-X [ Time Frame: Day 1 ]
    An EMED-X device will be used to assess plantar pressure when walking

  3. GaitMatII [ Time Frame: Day 1 ]
    temporal and spatial foot fall parameters will be quantified with the GaitMatII.
