Dealbreaker Warnings · Who Should Skip These
Critical biomechanical trade-offs to avoid buying the wrong shoe
adidas Terrex Agravic Speed Ultra
Skip Terrex Agravic Speed Ultra if your typical workout calls for a specialized racer rather than a durable daily trainer.
Salomon Thundercross
Skip Thundercross if your mileage includes paved asphalt or concrete; aggressive 5mm lugs wear rapidly on hard surfaces and cause harsh ground shock.
