I thought it would be a good idea to give a quick update on these boots as they have elicited quite a bit of interest. I’ve been wearing them every day for the last three months for dog walks. Arguably, they are overkill for walking the dog but they are just so comfortable that it’s difficult to motivate myself to use anything else.
The key to their comfort is their flexibility. While you couldn’t mistake wearing them for trainers, the sole unit is remarkably pliable. This is slightly surprising given that both the rubber tread and cushioning mid sole are quite thick. Nevertheless, they are very flexible, making walking very natural and effortless.
Despite this flexibility, they are also very stable. Some boots with thick midsoles are like walking on platforms, but not the Bioms. The deep tread has proved excellent on muddy paths. The rubber seems to be grippy on slippery hard surfaces (like our front path!), yet there is hardly any evidence of wear.
The Yak leather is lovely. It’s very soft and supple, yet there are hardly any marks on it. The colour has washed out a bit, giving a nice “distressed” patina. I’ve treated it once with Ecco leather conditioner and waterproofer. The leather still gets soaked quickly, but as I remarked on my Dartmoor trip, they seem to be quite waterproof. This will be tested on my next trip!
The rubber toe caps are a bit scuffed now, but I really like the toe caps and rand. While the toe box is quite stiff, the rand is very flexible, unlike those on many other boots. I know a lot of people claim that Goretex lined boots are very sweaty, but this has not been my experience with the Bioms.
The overall fit tends towards high volume, whereas my feet are rather dainty(!). By adding a volume reducer sole insert (Brasher 3mm), the fit is now nearly perfect. I’m also using some Sidas Comformable heat moulded insoles, which were originally for my ski boots. Despite being slightly short, they are fabulous and I’m thinking of getting another pair made.
The other tweak I’ve made is to change the laces. The ones supplied are too stretchy and I’ve swapped them for some more robust Scarpa laces. These are much better and allow for a firmer and more precise fit.
In conclusion, I really like these boots. My only hesitation is whether there will be a reoccurrence of the slight Achilles’ tendon bruising on my left foot that I suffered on Dartmoor last time. I will only know when I use them for a long walk. Hopefully I will have a definitive answer by February.
