1. A method associated with a toe sleeve comprising:
positioning a rupture disc within a sleeve port positioned through an inner sleeve;
forming a first piston area on a proximal end of the inner sleeve, the first piston area impacting a movement of the inner sleeve in a first direction; and
forming a second piston area on a distal end of the inner sleeve, the second piston area impacting the movement of the inner sleeve in a second direction, the first piston area and the second piston area being unbalanced;
positioning the first piston area within a recess, the recess being positioned within an external sleeve with a sidewall, the recess increasing an inner diameter of the sidewall until a downhole shoulder; and
restricting movement of the inner sleeve in the first direction via the downhole shoulder.
