This Supra is made using vulcanization technology and is a traditional handmade shoe. There may be slight glue overflow, which is a normal phenomenon and does not affect use. If you are very picky, please do not disturb. Thank you! In addition, it is stipulated that only environmentally friendly glue can be used, and there may be slight glue opening. If the glue is opened, please fill it in with glue in a timely manner. This is a possible phenomenon. I hope you can understand.
