H&M has an affordable Birkenstock alternative for you to try this summer for only $24.95. This slip-on sandal has two imitation leather straps that criss-cross over the foot, what seems to be a cork foot base, and then a rubber sole. If you really want to try the Birkenstock look without the price, this shoe is it. This is the cheapest version I have seen this season. Check it out at H&M.
