Hi Erica! As a running company, all our shoes, including the Glycerin StealthFit 20, are designed and tested with forward motion such as running and walking in mind. Activities that involve lateral movements are not something our shoes are built for and the life expectancy of the shoe (300-500 miles) is likely to decrease.
With that being said, for runners that still choose to use our shoes for more of these lateral movement activities or gym workouts, we tend to recommend a lower-profile, neutral style such as the Launch, Revel, or Levitate. We like to recommend neutral styles for these activities since additional support elements in the shoes can get in the way when used for more functional (especially lateral) movements.
