If you're squinting to find the differences between the SolarBoost and the Solar Glide, don't worry. You're not alone. These two models have plenty in common. They even share the same weight of 10.8 ounces and a midsole drop of 10mm. Just like the SolarBoost, the Solar Glide comes outfitted with a Solar Propulsion Guide. So where's the difference? The main differences are in the Torsion System and the upper. The Solar Glide's Torsion System doesn't extend up to the midfoot. So if you're looking for the more stable option, go for the SolarBoost. However, the Solar Glide's upper design is slightly more breathable, so choose wisely!
