I've always found it difficult trying to pin point a hole in neoprenes....try looking for a general area instead of the exact spot..stick your hand into the foot then submerge it in a tub with cold water, move the foot around for a few minutes and work the neoprene form the inside...if there's a leak then you should feel the water seep in..,pinch off the leaky area form the inside, turn it inside out and circle it with a felt marker, so when it's dry you'll know the general area to seal up. Apply a generous but even amount of Aqua seal to the effected area on the inside... then when it drys do the same on the ouside in the same general spot...I find this creates a pretty good seal...I get leaky neoprenes from float tubing, as the harness rubs against the seat from kicking...so I find I'm doing neoprene repairs a few times a season..One good thing I found by doing this, I've never had to repair the same area twice.. Hope this'll help.
