Crispi weren’t the first to do it.
Here’s a pair of very, very lightly used Hanwag Silstone gaiter GTX Boots in size 9.5 (44eur).
These boots have an internal lace system, then an outer zip, hardly any wear on the sole, just clearing the cupboards. There is also the TiZip Silicone grease. These are different gravy and a bargain at £147.50 including postage.
