In preparation for stocking Injinji toesocks (we’re so excited about this!), some due diligence was needed to purposefully select a range for the Blister Prevention online store. Tasked with this project, I was excited. But I knew it was going to be easier said than done.
Why Is Blister-Prevention Stocking Injinji Toesocks?For people who suffer with blisters between their toes! Please understand, toesocks are unique at the interdigital space only. Normally, in a standard sock, it’s a skin-skin interface between the toes. Toesocks turn it into a sock-sock interface. This is a significant change! Instantly, you can see there is going to be:
- Material capable of dealing with moisture, where normally there is none
- Cushioning between the toes, where normally there is none
- A double-sock system in place at the interdigital space
Types of Injinji ToesocksInjinji have a BIG range of toesocks. To help you choose the right one, Injinji names them with references to the activities, the weight and the height. And yet, I still find it difficult to choose or recommend one. They’ve also updated their range recently, so it was high time I ran my eye over the Injinji range again. In case you’re in the same boat, I thought I would share with you the table I used when choosing our own blister-specific Injinji range. I’ve left to the side the claims and features like “total foot utilisation” and “arch support”. I’ll just be taking into account the features and specifications that I believe are relevant to blister prevention. So, without further ado, let me walk you through the range we intend to stock and the reasoning behind our choices.
HeightLike all socks, Injinji toesocks can be classified according to their height. This one was easy because I know I want to offer all three heights to satisfy all my customers’ activities and preferences.
There’s also a “Hidden” sock which I’m excited to add as soon as Injinji replenish their stock. I’d personally like to wear these in my work shoes every day.
Weight LevelBetter known as thickness, Injinji offers 4 weights in the toe area:
- Lightweight Ultra-Thin (including the Liner Base Layer)
- Original Weight Thin
- Midweight Padded Cushioning
- Midweight with Padded Toes – This sock is identical to the Midweight sock but with a thicker terry padding at the toes.
- Padded +
- The best possible protection in each interdigital space
- Some padding and moisture-management between the toes but have wide feet and struggle at the best of times to find shoes wide enough in the toebox
ActivitiesInjinji has categorised their socks according to activity types. These include Run, UltraRun, Trail and Sport. Perhaps because Injinji’s largest customer base are runners, there are Run socks in all weight categories, with all socks in the Padded+ category being UltraRun socks. But Trail socks are only in the Padded category. Here are the specifics:
- Run socks: Ultra-Thin, Thin & Padded
- UltraRun socks: Padded+
- Trail socks: Padded
- Sport socks: Ultra-Thin & Thin
Fibre ContentFinally, there’s fibre content. Leaving the few wool socks Injinji offers to the side, just looking at their CoolMax range, there are subgroups within this range (run, trail, sport and liner). CoolMax is a well-known synthetic fibre developed to encourage moisture-wicking. Moisture-wicking is the facilitation of the movement of moisture from the skin surface, distributing it throughout the sock to enable evaporation through the shoe upper. The other fibres used are Nylon and Lycra – commonly used fibres in sock construction to ensure the sock is durable, stretchy and holds its shape over time. Each activity has a specific range of CoolMax percentage:
- Run has 28-30% Coolmax
- Ultrarun 29-33% CoolMax
- Trail has 39% Coolmax
- (Liner has 75% Coolmax)
- Sport has 78-85% Coolmax
What About Wool In Injinji Toesocks?I was going to leave wool out of our range. Just because there are so few in the Injinji range. Really, there’s just the:
- Liner Crew Wool: 74% wool
- Run Lightweight No-show: 66% wool
How Does One Choose a Sock to Prevent Blisters?When it comes to choosing a sock for blister prevention, my thoughts are these:
- DON’T choose a sock that doesn’t deal with moisture. Basically, don’t choose cotton. And in the absence of any research, but based on the fact that bamboo socks take forever to dry, avoid bamboo as well.
- DO choose a sock that’s comfortable. A lot of people like how a sock with wool in it feels. If nothing else, it provides better thermal insulation than synthetic materials. This will prove important in the cold. Other people like synthetic socks like Steigen. Some people will enjoy padding in certain sections of the sock, like that provided by Thorlo and many other brands. Others need a thin sock over and above all other features – they might have wide feet, or they might participate in endurance activities where swelling limits what they can get into their shoe.
Bringing ClarityMy job is to bring as much clarity to the subject as I can. But I can’t tell you the single best sock for preventing blisters. It’s a simple enough question, but I hope you can appreciate, there’s no simple answer. If you're not getting on with a particular sock, look at its properties, like thickness and fibre content. Then try a sock with different properties to see if it performs better for you in a particular setting (heat/cold, duration of activity, degree of swelling, level of perspiration or environmental water etc). One sock may not suit every application. And I wouldn't be afraid to try a "Sport" sock for running, or a "Run" sock for hiking etc. You'll need to conduct your own experimentation. However, if you continue to get blisters, you need to look further afield than simply your sock. My advice is to research the best strategies for the specific anatomical site of your blister (this is my area of expertise; this course is built around this topic) and choose from the suggested preventions. Rarely do I name a sock or even a sock feature as one of the best things you can do to prevent a particular blister. The exception is toesocks for interdigital blisters. And that’s why we’re stocking them in our online store.
So, Which Injinji Toesocks Are We Going to Stock?
The table below represents the properties of the socks we’ve chosen to stock in our online store. You may find this helpful in choosing your Injinji toesocks. For example, you may have extra wide feet and you want a toesock that doesn’t add excessive bulk in the toebox of your shoe. In this case, you’d go straight for the Ultra-Thin socks. Or, perhaps you want to maximise the moisture-wicking capability of your sock. In this case, you’d look for the socks with the highest CoolMax fibre content. Or perhaps if you like wearing crew length socks, you can see at a glance which socks you can choose from. You can then cross-reference socks that have extra padding at the toes (Padded+) to land on the best possible Injinji toesock for your purposes.p>
Here's a written explanation of my choices.
ThickestWithout even having to think about it, we’re going to stock the thickest toesocks. That is the UltraRun series in all 3 lengths: no-show, mini-crew and crew.
ThinnestAt the other end of the scale, we’ll have the thinnest toesocks in as many heights as are available. This includes:
- No-show (Run Lightweight No-show)
- There is no Mini-crew
- Liner Lightweight Crew (this is their Liner crew with a high 75% CoolMax)
- And we’ll stock their one and only “Hidden” PED sock which is named in their Sport range, but with 29% CoolMax, is more like a Run sock in terms of fibre composition (out of stock at the moment)
Highest CoolMax ContentThat means the Sport socks with 78-85% Coolmax. These two socks are in the Thin Original Weight sock range and are available in mini-crew and crew (no “no-show” available).
Midrange CoolMax ContentThis would mean the two Trail socks with 39% CoolMax. Both of these are in the Padded category, in mini-crew and crew (no “no-show” available).
Lowest CoolMax ContentThis would be the Run socks with 28-30% Coolmax. We’ll have the no-show and mini-crew from the Padded range (no “crew” available).
WoolFinally, we’ll stock the two wool toesocks Injinji offers. That is the:
- Run Lightweight No-show (66% Merino)
- Liner Crew Wool (74% Merino wool)
