Size 38.5 Worn Twice, too big for me.
Although 38.5 equates to about uk5.5, sportiva sizes are weird - VERY big for the size.
for example, I have size 8/8.5 feet in trainers, take anazasis in 7.5, but need to go down to at least a 38 (uk5) in miuras.
Try a pair on if you're thinking of buying!
RRP £70, YOURS FOR A MERE £50 ono
cheers
