The Dallas-based Sole Sisters site — an outgrowth of the Sole Sisters Film Project (“Every Shoe Has a Story, Every Woman Has Both”) — has given a hearty endorsement to the Winspear Opera House. That’s because architect Rem Koolhaas is the designer behind United Nude, a line of shoes heartily favored by the Sisters, especially for its famous launch product, “the Mobius shoe” (named after the Mobius strip because, with the ingenious shoe, a single strip of leather forms the sole, heel, foot-bed and upper).

So the Sisters marked this happy confluence of contemporary design by photographing a Mobius high heel with the Winspear.

OK, so you may have already detected the flaw in this celebration — ‘where the shoe pinches,’ as it were.

Koolhaas didn’t design the  Winspear. Sir Norman Foster did.

Koolhaas had a hand in the Wyly Theatre.
