Half-marathon training means logging longer weekly miles, and that extra time on your feet raises the stakes for comfort. A sock that bunches, rubs, or traps moisture can turn a promising training block into a cycle of blisters and lost days.
How we choose
This article highlights eight products—six running socks and two anti-chafe barriers—that address different friction points, foot shapes, and weather conditions. Each entry is selected for a specific use-case fit, whether you need toe separation, compression, merino warmth, or a preventive layer beyond the sock itself.

BalegaHidden Comfort Performance No Show Athletic Running Socks for Men and Women
What it is
Balega Hidden Comfort Performance No Show Athletic Running Socks are low-cut running socks with a seamless, hand-linked toe and a deep heel pocket.
Why it's worth it
The hand-linked seamless toe is designed to eliminate the abrasion across the top of the foot, and the deep heel pocket is knitted to stop the sock sliding down as you run. The drynamix moisture-wicking yarn is intended to keep feet cool and dry. This is well suited to half-marathon training for runners who want a low-cut sock that stays in place.
Caveat
The no-show cut stops at the ankle, so runners who want calf coverage or Achilles protection from the sock will need a mini-crew or crew height.
FeeturesElite Light Cushion No Show Tab Sock Wave
What it is
Feetures Elite Light Cushion No Show Tab Sock Wave is an anatomical left/right running sock with targeted compression and light underfoot cushioning.
Why it's worth it
The left/right anatomical shape and targeted compression work together to hold the sock close to the foot, and Feetures states this reduces the risk of blisters. The light cushion adds impact protection without taking up much room inside the shoe. This is a good fit for tempo runs and marathon pace work where a secure, low-bulk fit matters.
Caveat
The light cushion is only a thin layer, so runners looking for high-volume impact protection on downhills may want a max-cushion style.
InjinjiMen's Run Midweight No Show Toesocks
What it is
Injinji Men's Run Midweight No Show Toesocks are five-toe running socks with a midweight cushion and a no-show length.
Why it's worth it
Each toe is covered individually, so toes do not rub against each other while you run. That addresses one of the most common starting points for hot spots, and the midweight cushion gives more underfoot padding than an ultra-light racer. This is well suited to half-marathon training for runners who get blisters between the toes rather than on the heel or ball of the foot.
Caveat
The five-toe design takes longer to pull on than a regular sock, and the fabric between toes can feel unusual at first.
SwiftwickASPIRE Zero No Show Performance Socks
What it is
Swiftwick ASPIRE Zero No Show Performance Socks are ultra-light, thin no-show socks with firm compression and moisture-wicking olefin fibers.
Why it's worth it
The Y-shaped heel is designed to hug the foot and stop the sock bunching, which reduces the fold-and-rub friction that can lead to blisters. The ultra-light knit and channeled upper are aimed at breathability, while the olefin fibers wick moisture to keep feet dry. This is a good fit for long runs in warm weather where a thinner sock keeps shoes feeling roomier.
Caveat
The firm compression fit is snug by design, so runners who prefer a loose, relaxed sock may find it too tight.
BOMBASWomen's Originals Ankle Socks, (Grey/Blue)
What it is
Bombas Women's Originals Ankle Socks are cotton ankle socks with a seamless toe, blister tab, and honeycomb arch support.
Why it's worth it
The blister tab sits behind the heel to shield the area where the shoe collar often rubs, and the seamless toe avoids a ridge at the front of the sock. Honeycomb arch support helps the sock stay anchored through the midfoot. These are a good fit for runners who want an ankle sock that can move between training runs and everyday wear.
Caveat
Because these are everyday cotton ankle socks rather than a race-specific performance knit, they are less ideal for heavy-sweat speed sessions.
Darn Tough VermontDarn Tough Women's Run No Show Tab Ultra-Lightweight Running Sock (Style 1047) -
What it is
Darn Tough Women's Run No Show Tab Ultra-Lightweight Running Sock (Style 1047) is a merino-wool blend no-show running sock with light underfoot cushioning.
Why it's worth it
The 49% merino wool content makes this a good option for cold-weather miles, while the nylon adds durability. Darn Tough specifies True Seamless technology for a smooth toe, and the no-show tab height sits low enough to work with road shoes. It is a good fit for runners who want a wool sock without a thick, bulky cushion.
Caveat
The 1047 style is a women's-specific fit, so if you need men's sizing this is not the pair to order.
Body Glide Original Anti Chafe Balm | No Chafing Stick | Prevent Arm, Chest, Butt, Thigh, Ball Chafing & Irritation | Trusted Skin Protection Since 1996 |1.5oz
What it is
Body Glide Original Anti Chafe Balm is a solid anti-chafe stick that comes in a 1.5 oz twist-up tube.
Why it's worth it
The solid stick applies directly to skin, so you can coat heels, toes and other known hot spots before pulling on socks. The listing says it prevents and relieves hot spots on feet and washes off with soap. It is well suited to runners who want a preventive layer of protection in addition to a seamless sock.
Caveat
This is a preventive product, so an existing blister still needs a dressing rather than another layer of balm.
2TomsSportShield, All-Day Anti Chafe and Blister Prevention, Waterproof | Soothing Anti-Chafe Prevention for Chafing & Skin Irritations
What it is
2Toms SportShield is a roll-on anti-chafe and blister prevention product in a 1.5 fl oz bottle.
Why it's worth it
The roll-on format makes it easy to cover a larger area evenly, including the tops of toes and the back of heels. The listing describes the formula as waterproof and sweatproof, which is useful for summer training when feet are more likely to get damp. This is a good fit for half-marathon runners who want anti-chafe protection that stays put through longer efforts.
Caveat
The roll-on must be applied before you put on socks, so it isn't a mid-run fix once rubbing has started.
How to choose
How to choose the right anti-blister running socks for half-marathon training blocks
Takeaway
The right anti-blister setup depends on where friction starts, what the weather demands, and how much cushion your shoes can accommodate. Match the product to the problem, and you reduce the chance of a blister interrupting your training.
