I had a pair of Nike's that were very similiar construction. All around biking shoe that you could walk in. Bought mine around 1990. I would guess yours are of the same vintage. I really liked them but they were'nt the most durable of shoes. Wore them out in about two years of low mileage riding.
Did they have any more? My Avocets are just about worn out.
This was the only pair I saw. Frankly, they're less comfortable than my MTB clipless shoes (which, though just as stiff, have a bit of a slope at the front to allow a more natural gait), so I don't expect I'll be wearing them much anyway.
