A computer-assisted method of transitioning from a first footwear type to a second footwear type, comprising: receiving data, at a processor of an electronic device, from a sensor system configured to sense biomechanical movement of a foot of a user during an athletic activity, the sensor system comprising a plurality of force sensors engaged with an article of footwear of the second footwear type and configured to sense force exerted by a foot of a user, and an electronic module configured to collect data based on force input from the plurality of force sensors and to wirelessly transmit data generated by the sensor system; recording a plurality of data points of the user during an athletic activity session comprising the athletic activity; analyzing the data, by the processor, to determine whether the data is indicative of a deviation from a footstrike pattern, wherein the footstrike pattern corresponds to a preferred footstrike of the second footwear type and differs from a preferred footstrike of the first footwear type; generating an indication to the user, by the processor, upon completion of the athletic activity session when the deviation from the footstrike pattern corresponding to the preferred footstrike of the second footwear type is determined to exist; and modifying a duration of a transitional coaching program configured to transition the user from the first footwear type to the second footwear type based on at least one of an amount of recorded deviations, a total time of recorded data, and a total distance of recorded data, wherein the transitional coaching program is implemented to be executable on the electronic device, and wherein the transitional coaching program is configured to transition the user from the first footwear type to the second footwear type. receiving data, at a processor of an electronic device, from a sensor system configured to sense biomechanical movement of a foot of a user during an athletic activity, the sensor system comprising a plurality of force sensors engaged with an article of footwear of the second footwear type and configured to sense force exerted by a foot of a user, and an electronic module configured to collect data based on force input from the plurality of force sensors and to wirelessly transmit data generated by the sensor system; recording a plurality of data points of the user during an athletic activity session comprising the athletic activity; analyzing the data, by the processor, to determine whether the data is indicative of a deviation from a footstrike pattern, wherein the footstrike pattern corresponds to a preferred footstrike of the second footwear type and differs from a preferred footstrike of the first footwear type; generating an indication to the user, by the processor, upon completion of the athletic activity session when the deviation from the footstrike pattern corresponding to the preferred footstrike of the second footwear type is determined to exist; and modifying a duration of a transitional coaching program configured to transition the user from the first footwear type to the second footwear type based on at least one of an amount of recorded deviations, a total time of recorded data, and a total distance of recorded data, wherein the transitional coaching program is implemented to be executable on the electronic device, and wherein the transitional coaching program is configured to transition the user from the first footwear type to the second footwear type. <EOS>
