Not bad if you're just looking for something cheap to replace with and only ride occasionally. Really depends on the foam as well. Older style open foam grips were usually fairly basic and could break down quickly compared to a rubber grip or get kind of hard and crunchy if low use and got old. They weren't all that comfortable but also not typically uncomfortable. Newer, high density foam can be quite nice, still not quite as durable as rubber but often more cushioning for the same thickness as they are less dense then rubber. When wet they're also more prone to moving on the bars. But very good vibration dampening. Up side to rubber is that you can get better shaped grips for even more comfort but at still greater cost. For a low use hybrid, wouldn't hesitate to get a high density foam, for higher mileage I'd spend more.
