The Defyance has left production and is a retired model for us now. We have two models that match some of the benefits from the Defyance.
If you enjoyed the cushioning and drop from heel to toe of the Defyance then we would suggest our Ghost as a good option. The Ghost will match the fit and cushion level but with added room in the toe box for a little more wiggle room. The second closest option is the Dyad model. The Dyad has the stability benefits of the Defyance but with a lower arch.
Depending on which features you loved in the Defyance will help to find which model may be better for your needs.
