Brief Summary:
This research is being conducted to determine whether use of an arch-supporting insole during pregnancy prevents alterations in foot structure and lower limb rotational movements. The investigators hypothesize that the arch collapse during pregnancy will be significantly reduced in women randomized to use the supportive insole compared with women randomized to the control group.

Primary Outcome Measures :
  1. Change in Arch Drop [ Time Frame: baseline, 8 weeks postpartum ]
    Measurement of Arch Drop (Sitting arch height minus standing arch height) using Arch Height Index Measurement System

Secondary Outcome Measures :
  1. Change in Arch Rigidity [ Time Frame: baseline, 8 weeks postpartum ]
    The arch rigidity index, a measure of the ability of the foot to maintain the arch when weight-bearing, was determined by dividing the standing AHI by the seated AHI. A value of 1.0 would indicate a perfectly rigid arch, while smaller values would indicate a more flexible arch.

  2. Change in CPEI (3mph) [ Time Frame: baseline, 8 weeks postpartum ]
    The Center of Pressure Excursion Index (CPEI) is a measurement of the lateral displacement of the center of pressure curve from a reference line drawn from the initial to the final centers of pressure during stance phase of gait, and standardized to the width of the anterior third of the foot during pedobarography.
