You have more up to date info than the Sidi web site.... I'd assumed that since they were switching from nylon to carbon soles on the Genius 5's that they'd also be offering only 39's and up - as all their other carbon shoes are that sizing. It's nice to know that they will be still offering 37's as I rather like my Sidis. Not so sure I care for the flowers..... but black broil your feet - my husband had actual burns! on the tops of his feet from one long hot race..
