The Aero Spark sits in the middle of Skechers' AERO range and is the one meant for ordinary weeks. Dual-density Hyper Burst Ice gives it a 36 mm heel, a carbon-infused plate stiffens the toe-off, and the 6 mm drop lands where most trainers do. Easy days, steady days and the long one at the end of them are all inside what it does well.
It suits you if you want a single pair that covers most of your mileage without asking for a decision. The Goodyear outsole wears slowly and the fit is roomier than a race shoe's.
It is neither the lightest nor the softest thing Skechers makes. At 275 grams it sits in the middle on purpose — the range has both a lighter shoe and a taller one if you want either.
