I have challenging feet. Nerve damage, no arches and a toe that points to the opposite foot instead of the more common bunion. Buying or having shoes made to accommodate these issues is hit or miss, motly miss. When I find a shoe or slipper that I can actually tolerate walking in for a length of time, its an occasion to buy as many pairs as I can budget for over a period of time. This is is my second purchase of these slippers. Not cheap but worth every cent. Cool and comfortable in 100+ summer temps, reassuringly warm during winter. These are the slippers I take with me when visiting friends homes where street shoes aren't worn indoors. And these are the slippers that inspired me to look for woolen street shoes (Allbirds highly recommended for support and comfort).
