I would try a pair on before ordering, if you can. Older Tretorns, anyway, have a funny shape/silhouette. I think they have more in common with Keds than Chucks.
Yes, the old Tretorns were more like those keds for women. Though Tretorn did (does?) make a pair that was slightly (but only slightly) more shaped for the male foot. The old mens Tretorns came with white "stripe" or navy. I think they were a compfortable shoe, high-quality, made in Sweden (??) I think -- but for sport, there are better shoes. For fashion, I'll let you judge. The women's had a stripe of pink, green, plaid, white, or a lighter blue. For a long time, they seemed to have limited distribution to small tennis shops, clubs, etc. More popular in sections of the east coast or mid-west (places like Lake Forest) then anywhere else. At least this was my impression.
