Very good exercise equipment. Its not durable. I am an iOS User; I am using iPhone, Apple Watch & other Apple products. 5 which was offered but turned out to be an 11 or size 43. Im shocked to tell you these shoes are falling apart😱Ive worn Birkenstock forever and they usually last years! I can be a bit critical when it comes to kitchen items and first impression I was happy with my purchase. Always a little wary of buying clothing/footwear online because you never know how its going to fit. I think it runs kinda small . But that’s okay! He usually wears 11.
