For numbness with the groceries, I really like my SQlab saddle. I have the "604 Active", but they make a ton of different styles.

I've tried a lot of saddles, and the common denominator with numbess for me seemed to be pressure from the area from the front of the nose to about midway back. It's not about hardness or softness of the sit bone area...but the material in front of the sit bone area. Even with "firm" saddles, my shape must just keep pressure down on the saddle in that area. So I started looking at noseless saddles. I didn't quite like the compromises with those...and then I found the SQlab folks who make saddles that still have a nose, but they're stepped down from the sit bone area. It looked interesting enough to try (and a lot of the marketing wank on their website makes sense).

This saddle works a treat for me...I can lean forward on my bike without smashing my grapes. Everything is just more comfortable (everything). It's pretty crazy to discover how interconnected nerves and bloodflow are in your body, because even hand nerves seem better (though I do like playing with bar ends to see what other hand positions do well for me).
