H&M Black Block Heeled slingbacks with square toe

Black slingbacks with block heel and pointed squared off toes. Ankle strap elasticized at back, saying lining, heel height 2.5 inches. Wore once. H&M always says a size 38 is a US 7, but I’m a true size 8 and in my experience, the 38 from H&M is an 8. The site even said to size down on this pair, but I can say the 38 fits like an 8. If you have a wide foot, these might be too tight.
