These activities are grouped together as the body movements of these sports are very similar, the body action of twisting, turning accelerating and decelerating quickly in all directions which is a tough job for the feet to adapt to. Jumping for the ball and returning to the ground creates a huge impact of pressure on the feet and the action of sliding from side to side of the foot in the shoe is one of the contributing factors for blisters on the feet. Add heat, humidity and the differing ground surfaces into the equation and blisters are almost a guaranteed outcome.
The balls of the feet, little toes and heels tend to suffer more with blisters with these sports especially if the same sport is played in and outside on different playing surfaces whilst wearing the same shoes. Ideally, a change of footwear for different playing surfaces is preferable. Ground reaction forces will be different and will affect the pressure loading for the feet which can be a contributing factor to blisters.
If you just get blisters on one foot, it may be due to one foot being larger than the other, which is quite normal, it could be that you have a favoured side that you would always instinctively use first. Therefore your leading arm and leg/foot could be receive more pressure than the less favoured foot. Changing your technique slightly and being aware of body symmetry could help improve your posture and foot pressure.
Poron insoles are great shock absorbers they will reduce the shear applied to the soles of the feet. Poron “vive” insoles would be a good choice for these sport, due to the nature of the insole not only absorbing shock but by giving energy back to the next step or jump.( link to poron vid)
Lace locking is essential for retaining the foot in the shoe and preventing it moving around too much.
Best socks for tennis
Wicking socks should always be considered as they are the best at keeping the moisture away from the skin and decreasing the chance of blister formation, Injinji socks are useful if you are struggling with blisters in between the toes, although there needs to be extra room in the front of the shoe to allow for the extra material in the sock
Armaskin liner socks. Are great as preventing blisters all around the foot, If you have blisters around the toes, then Injinji socks would help prevent those particular type along with foot care in keeping the toe nails short. Heel Blisters caused by heel movement in the shoe, then lace locking will help.
Engo patches are placed into the shoe either at the back of the shoe, around the edges or underneath the balls of the feet but not under the big toe joint. These will help reduce the friction applied to the skin from the footwear.
2toms Blistershield powder can work really well by itself on the skin as a prevention measure or after the blister prevention tape has been applied, reducing the friction applied to that area.
Taping the skin with Hypafix and KT Pro tapes are great blister prevention measures along with2toms blister powder.
Silopos ®Gel Digi caps are excellent for preventing blisters on one toe, especially the little toes
Epitact epithelium gel ovals are perfect for preventing blisters on the heel and arches of the foot, there are reusable for up to five times and need to be secured to the skin with Hypafix tape.
