Hi Ger,
The swelling is very difficult in that it makes the leg so cumbersome and finding pants and footwear a huge challenge! My husband took pills for swelling in the beginning (can't remember the ones he tried) but it did not help. Sounds like he wears a similar sandal as you. We buy a sports sandal with a velcro strap and just add the right length of additional velcro to the existing strap so that it fits. We do need to find a good boot for the winter that is warm and that has a sole. I had a lady make an insulated bootie but it did not have a sole so the fabric was quickly eaten away from the road salt. He does not bear weight on the leg..he just touches it to the ground with each step but once the fabric deteriorated, it is no longer warm. I need to ask her if she is able to make a soled boot. I am going to check out ShoeBuy as well. Thanks and take care!
