Preheat the air fryer to 400°F (200°C) for 5 minutes.
Pat the chicken thighs dry with paper towels to ensure crispy skin.
In a small bowl, mix the salt, black pepper, garlic powder, and smoked paprika.
Rub the spice mixture evenly over both sides of each chicken thigh.
Drizzle olive oil over the chicken thighs and rub to coat evenly.
Place the chicken thighs skin-side down in the air fryer basket in a single layer. Cook for 10 minutes.
While the chicken cooks, prepare the honey glaze by whisking together honey, soy sauce, and apple cider vinegar in a small bowl.
After 10 minutes, flip the chicken thighs skin-side up and brush half of the honey glaze over the skin.
Continue cooking for another 8-10 minutes until the internal temperature reaches 165°F (74°C) and the skin is crispy.
Brush the remaining honey glaze over the chicken thighs just before serving.
