Thank you both, for your feedback! I may just go ahead and purchase both the LG and the Sole Slim footbeds. I can try one in my road shoes, and the other in my MTB shoes which I use for spinning classes...and see which one I like better.

In regards to the comment on Dansko shoes...yes, I have already discovered Dansko's!!! LOVE 'EM! I wear them exclusively as my work shoe. I have plantar fasciitis in my left foot, so good shoes are important to me. When I'm lounging around at home, I absolutely MUST have my Crocs Mammoth's on, otherwise my feet will protest loudly.
