Fits with or without neoprene shoes

Without shoes I slide quite far purely in the fin and close the tape on the heel almost closest setting. The rubber is very soft and conforms to foot well.

With shoes (neoprene booties) I slip not so far purely in the fin. The material is stretchable and adapts the shoe to something. The heel strap I close then a little further.

For my shoe sizes both variants are possible with this fin, I would buy it again also.
