Footsteps is almost irrelevant. In the 12 years they’ve been around they’ve handled about 100 people over a period of over a decade. And most of those 100 were effectively not frum before they hooked up with the reshoyim at Footsteps.
I can’t tell you about the US, but in the UK, the sister program of Footsteps is not irrelevant. I know firsthand of victims who were still Shoimer Torah uMitzvos – albeit in a fragile, shattered framework – until Footsteps got their hands on them.
