But the thing is-your feet can really get hot and sweaty because the material used for jelly shoes are made from plastic and are non-breathable. Jelly shoes are recommended for use if you are in a beach or a pool but these are not really walking shoes. But these cute shoes can come in cheap and inexpensive so it won’t hurt you to buy a pair! There are a lot of shoe brands that are selling jelly shoes for a lot less than Marc Jacobs.
