I may have had a pair of those--I did have a pair of blue Etonics in that era and do remember stained socks somewhere along the line. I liked the shoes.
Line of classics
1977. Those Red Tigers like Jim Fixx's on the Complete Runner. Got issued a pair of those from our team in 1977 and ran in them all school year, so probably another 2000 miles.
1977-78. Tiger Jayhawk spikes and flats. They were the bomb.
1978-80. Almost completely sucked in by Nike, and had the suite of classics: Elite, LDV, Waffle Trainer, Oregon Waffle, Vanquor (spelling? but they good spikes). I tried a pair of Brooks Vantage and within two weeks broke my foot when I stepped off a curb and it twisted--blamed it on the Varus wedge.
81-82--about the right time for the blue Etonics
83-won a pair of Nike Pegasus--about their first air shoe-- and promptly got ITBS which knocked me out for the better part of a year.
84 and beyond--Brooks, Asics
