Hey Buddy,
Just a caution not to wear dress or other polished shoes with coco mats (nor Sisal) cuz they'll wear off the finish/color on the heels & sides in short order by rubbing on the mats. Back in the day when my 914 was my DD, I had to take off my dress shoes for work in order to not show up to a biz meeting with scuffed up shoes - NOT a good impression!
The ones with rubber heel pads help, but shoes can still get scuffed heels & sides if you rest your feet in the other areas.
If you don't find a set of used or NOS ones cheap, then you might sign up for cocomats.com & the various other coco/sisal mat makers' email lists for sales.
Another option which is much more comfortable for both shoes & barefootin' are the plush carpet mats from Lloyd & others - which also may be some available used/NOS from members, or do the emails sale thing from SMC, AA, etc. when they have sales on them.
... or Berber like Mike's set, or loop pile - but neither is as cushy as plush - but it's what you want for your footies.
Good Luck!
Tom
